Links to custom error messages

Some of the comments contain the phrase "with custom error message", where the last three words are a link to the relevant message. Brian Jason Drake 06:04, 5 March 2009 (UTC)

Link format

Two formats for the phrase are in use:

1. , with custom error message
2. (with custom error message)

Can we get a consensus to use just one of these?

Once a format has been chosen, someone can call an admin to add more links, as described below.

Aggregation and deposition of fullerene nanoparticles in aquatic system

I learned of this blacklist when I attempted to move Aggregation and Deposition of Fullerene Nanoparticles in Aquatic system to Aggregation and deposition of fullerene nanoparticles in aquatic system. What's the issue here? —Tamfang (talk) 20:17, 6 March 2009 (UTC)

NawlinWiki screwed up when he added something to the blacklist. --Carnildo (talk) 23:25, 6 March 2009 (UTC)

Faggots (novel) → Faggots

I'm a bit baffled. Faggots is currently a redirect to Faggot but AFAIK there's nothing else called "Faggots". Normally in a case like this we'd have the article located under its correct name with a hat note but "Faggots" as a standalone comes up on the blacklist? Why? Otto4711 (talk) 19:05, 15 March 2009 (UTC)

It's to prevent vandals from moving pages to titles containing the word "faggot". Since this is a legitimate page move, you can ask an admin to do it for you at WP:AN. Admins can override the blacklist. — jwillbur 21:51, 16 March 2009 (UTC)

Error message standardisation

The current error messages are so different that, unless they knew better, people would probably guess that they came from different sites. Also, the last three of the messages listed above (particularly titleblacklist-forbidden-new-account) are unclear.

I suggest that we make each of them consist of a specific message followed by a template that would be the same on all the error messages. This template would explain about how administrators can override the blacklist, how you should be clear when contacting admins, etc. Brian Jason Drake 06:17, 12 April 2009 (UTC)

I drafted such a template at Mediawiki talk:Titleblacklist/Error message template. Brian Jason Drake 06:29, 12 April 2009 (UTC)

.*babyfuck*

Since a few moments ago we had a vandalisim-only user making pages under variations of that title, only appearing to contain the flag of Germany. ViperSnake151  Talk  17:55, 20 April 2009 (UTC)

Done, but:

• I assume you wanted to say

  .*babyfuck.*

• What user? One user? Anon, or multiple accounts? Or talk pages?

Amalthea 18:02, 20 April 2009 (UTC)

Having had a look I only found the edits of Metrovicky (talk · contribs). Why wasn't blocking him enough? --Amalthea 18:07, 20 April 2009 (UTC)

Well, it is a ridiclous title for ANY article, so in case anyone else brings it up, an article was previously speedied as nonsense there too. ViperSnake151  Talk  01:24, 22 April 2009 (UTC)

Still, if it can be stopped by blocking then that should be tried first. We should stick to recurring title patterns here, attempting to build a list of all vandalistic page titles here is rather futile and would eventually start slowing down edits, too. --Amalthea 08:54, 22 April 2009 (UTC)

Archive errors

I've noticed some users try to create archives using the wrong slash. Could someone double-check and then add the following regex? Thanks. MBisanz ^talk 20:40, 1 May 2009 (UTC)

#poorly-made archives
.*\\[Aa]rchive.*

Like...

# POORLY-MADE ARCHIVES

Which is already on the blacklist. Some say that taking others' work without appropriate attribution is plagiarism. --MZMcBride (talk) 20:44, 1 May 2009 (UTC)

It was from the testwiki and seemed like a good idea to move it here since I was still seeing improper archives, must have been old archives. MBisanz ^talk 20:45, 1 May 2009 (UTC)

ℓ

An obscure character for sure, but it seems to be used in obscure mathematics, particularly this article which was created at the {{wrongtitle}} due to this blacklist. All other articles refer to it using an overly long piped link. — CharlotteWebb 19:30, 3 May 2009 (UTC)

I've moved the article. You think that's needed often enough to remove it from that rule? I don't know enough about these rules, or the related vandalism to have an opinion on the usefulness of that rule. Amalthea 19:56, 3 May 2009 (UTC)

I'd turn that around and ask whether it's abused often enough (if at all) to justify keeping it blacklisted, and would further suggest that we should err on the side of "not impeding normal edits". I've identified a problem with part of this blacklist and I realize it is of a narrow scope, but the benefit remains unestablished. I'm reminded of the time I was prevented from using a title containing the year 1469, not due to the sexual aspects of "69" mind you, but because 1469 somehow looks like part of a 1337 spelling of "HAGGER". It could be like one of those Magic Eye puzzles where the infamous word would in fact leap right out at me from every direction if only I'd been reverting vandalism for 27 hours straight, but I'm not seeing it (thankfully, I might add—I mean when I start seeing mysterious winged creatures that dissolve into thin air rather than hitting my windshield at least I know it's time to pull over and take a nap). A few diffucklties are understandable here and there, but the dozen or so other times I've gotten similar error messages were for reasons that made even less sense. And still this does next to nothing in terms of reducing the amount of page-move vandalism. — CharlotteWebb 20:34, 3 May 2009 (UTC)

I've removed the character from the blacklist. As a side note, it was in the "Unicode lookalikes" set rather than any of the anti-Hagger entries. --Carnildo (talk) 21:18, 3 May 2009 (UTC)

Alright, thanks but do we really need that section if it's not being abused for haggerific or other nefarious purposes? Granted there's a fair bit to be said about self-fulfilling prophecy. — CharlotteWebb 15:17, 4 May 2009 (UTC)

It's been there for a year, but I wouldn't mind removing it, plus the "select mathematical operators". Let's wait a couple days, and if nobody screams bloody murder we'll throw it out. Amalthea 15:59, 4 May 2009 (UTC)

I'd leave the letters such as "ℊ" and "ℯ" that are easy to mistake for their Latin equivalents. --Carnildo (talk) 23:47, 4 May 2009 (UTC)

Well yes, but there are a gazillion of such symbols: Just from one of the hagger rules, Α Ά Ὰ Ἁ Ἄ Ἂ Ἅ Ἃ are all easy to mistake for an A. It seems pointless to even start listing them in such a black&white rule. Amalthea 11:53, 12 May 2009 (UTC)

Remove Bukisa From Blocklist

Please remove Bukisa from the Title Blacklist.

"User:BlackWalker/Bukisa" cannot be moved to "Http://en.wikipedia.org/Bukisa", because the title "Http://en.wikipedia.org/Bukisa" is on the title blacklist. If you feel that this move is valid, please consider requesting the move first." Is the error that comes up when I try to create this wikipedia article.

There is no reason why this article topic is blocked. Please let me create this page. Thanks! --BlackWalker 24 June 2009

It's blocked because URLs aren't allowed in article names. If you want to move it, move it to "Bukisa". I recommend not doing so yet, though: the article doesn't cite any good third-party references to establish notability, so the article may be deleted. --Carnildo (talk) 01:31, 25 June 2009 (UTC)

Hi Carnildo. I put it under "Bukisa", however when I do it is coming up on BlackList. This doesn't make sense, Bukisa is the name of the company, it's website is www.bukisa.com. I have cited referenced both Reuters and Mashable, which are worthy sources that Bukisa is a legitimate company. This is a company, not a URL. Thanks! -- BlackWalker 28 June 2009 —Preceding undated comment added 12:42, 28 June 2009 (UTC).

None of the blacklist rules prohibit moving it to "Bukisa". --Carnildo (talk) 19:42, 28 June 2009 (UTC)

Hi Carnido. When I try to move it to http://en.wikipedia.org/bukisa, I get the following error message: "User:BlackWalker/Bukisa" cannot be moved to "Http://en.wikipedia.org/bukisa", because the title "Http://en.wikipedia.org/bukisa" is on the title blacklist. If you feel that this move is valid, please consider requesting the move first." Thanks BlackWalker 29 June 2009 —Preceding undated comment added 12:46, 29 June 2009 (UTC).

When you are trying to move it, enter just "Bukisa" in the "To new title" field, not "http://en.wikipedia.org/bukisa". — jwillbur 20:44, 29 June 2009 (UTC)

Durarara and similar

• I brought this up in Wikipedia:Village pump (miscellaneous) and I was referred to here. See Talk:Dhurarara!!#Move? for a complaint about titles Durarara!! and Dulalala!! being apparently auto-blacklisted -- because of the repeated syllable? Anthony Appleyard (talk) 13:51, 7 July 2009 (UTC)
• Yes, any title with repeating exclamation points are on the blacklist, a favorite frequent technique of vandals in the past. As an admin, you should not be affected by the blacklist and should be able to make the appropriate move yourself – although I currently fail to see any consensus on Talk:Dhurarara!! at this time. Cheers. Zzyzx11 (talk) 14:47, 7 July 2009 (UTC)
• Is there any way that, given a possible page title, I can quickly find if it is on the blacklist? Not by trying to create the page, as I am an admin. Anthony Appleyard (talk) 18:52, 7 July 2009 (UTC)

  Unless you want to scan through all the comment lines on the MediaWiki:Titleblacklist (all phrases starting with hash "#"), the only quick and easy way is to create an alternate account as per WP:SOCK#LEGIT. I always recommend it to any admin who wants to either experience how Wikipedia functions as a regular user, or those who use public or shared computers and need a guaranteed way to keep their sysop account secure. Zzyzx11 (talk) 02:47, 8 July 2009 (UTC)

• If you've got Perl installed on your computer, the script at User:Carnildo/wiki-regex-tester.pl can be used to test a title against the blacklist. --Carnildo (talk) 05:04, 8 July 2009 (UTC)

Please

Hi, you may or may not remember me better as Jimi Pager, someone who has had all their editing rights revoked supposedly because of abuse of multiple accounts. I can assure you that I (originally Jimi Pager, now iamtheggman) did not even have more than one account that I ever regularly use, let alone abuse that privilege. If you could, please be so kind as to re-instate the editing rights of Jimi Pager, seeing as no vandialism has been committed under that name. Thank you, in advance.

BMP-centrism and multilingual nonsupport

Could somebody explain why letters above 0xFFFF should be feared more than any other non-Latin script? .*[^\0-\x{FFFF}].* prevents me from creating an appropriate redirect at 𐌲𐌿𐍄𐌹𐍃𐌺, whereas 日本語 links to Japanese, עברית to Hebrew, etc. Despite the usual contrary rhetoric I believe these are likely search terms as they commonly appear in the interwiki sidebar, and people will want to know what they mean. — CharlotteWebb 22:01, 23 August 2009 (UTC)

Filenames consisting of numbers only

{{editprotected}} Please add the following lines to here:

#Numbers only in file names
File:\d+\.\w+ <reupload|errmsg=titleblacklist-custom-imagename>

This is to block the uploading of filenames that consist only of numbers like "File:0038849489.jpg", "File:838293.png" and the like (but still allowing to reupload over existing images), giving the people a specific warning. I consider this to be uncontroversial, as I don't think that anyone thinks that this makes sense to use such filenames, and also it's no longer possible to just move such filenames over to Commons. Thank you. --The Evil IP address (talk) 12:47, 12 October 2009 (UTC)

Could someone familiar with this page, double-check the regex code? — Martin (MSGJ · talk) 16:30, 12 October 2009 (UTC)

Checked the Regex against this handy AWB guide on it and it seems correct:

\d+ (more than one digit) \. (is the dot before the file type) \w+ (one or more letters, e.g. "jpg")

However I think we should use a more descriptive error message than "titleblacklist-custom-imagename" unless that functions in a way I'm not expecting. Rambo's Revenge (talk) 19:25, 12 October 2009 (UTC)

It will bring up this error message. I'll add the entry to the blacklist. --Carnildo (talk) 23:31, 12 October 2009 (UTC)

Wow, I must have been fairly thick not to figure that one out. Thanks for taking the time to explain. Rambo's Revenge (talk) 20:25, 13 October 2009 (UTC)

Chestnut Sac-Winged Bat

I just tried to move the page on the Chestnut Sac-Winged Bat to Chestnut Sac-winged Bat to correct the spelling, but this for some reason hit the title blacklist. I don't see any reason why it should. Why is this and what can be done about it? Ucucha 14:01, 25 October 2009 (UTC)

I've removed the badly-written blacklist entry involved. --Carnildo (talk) 22:05, 25 October 2009 (UTC)

prevent runs of multiple single quotes ( ' )

It regularly happens that less-experienced editors create page titles with runs of single quotes in them, either because they are trying to compose a double-quote mark that way, because they are trying to add wikimarkup to a page title, or because they got the precedence of wikimarkup wrong (e.g., trying to emphasize within brackets). In nearly all of these cases, the page title will start with such a run of single quotes. Can we possibly blacklist either

'{2}

or

^'{2}

as a way to prevent these mistaken creations? — Gavia immer (talk) 02:59, 27 November 2009 (UTC)

ꆇꉙ and 𐌲𐌿𐍄𐌹𐍃𐌺

Why are ꆇꉙ and 𐌲𐌿𐍄𐌹𐍃𐌺 blacklisted? I would like to redirect ꆇꉙ to Nuosu language and 𐌲𐌿𐍄𐌹𐍃𐌺 to Gothic language. AGENT SMITH 06:20, 13 December 2009 (UTC)

ꆇꉙ is triggering the "unused obscure scripts" entry. I've removed that one, since the scripts clearly *are* used. 𐌲𐌿𐍄𐌹𐍃𐌺 is triggering both that one and the "characters outside the basic multilingual plane" entry. I've left that one alone, since I don't know how useful page titles outside the BMP are: I doubt many people have fonts that can display those characters. --Carnildo (talk) 08:56, 13 December 2009 (UTC)

The Gothic runes are used in the Gothic alphabet article and all of its sub-articles (e.g., 𐌲, 𐌿, 𐍄, etc.). AGENT SMITH 21:17, 13 December 2009 (UTC)

Odd blacklisting

I tried to move Samurai Sentai Shinkenger vs. Go-onger Ginmaku Bang!! to Samurai Sentai Shinkenger vs. Go-onger: GinmakuBang!!, but I'm getting a message that this is on the title blacklist. Why is this being blocked at all?—Ryūlóng (竜龙) 23:32, 31 January 2010 (UTC)

I've a hunch that it's because it's not allowed to move a page to a title ending in two excalamtion points, even though it is allowed to create such a page. Even though the original title also had two exclamation points, the Title blacklist doesnt seem to have a way of checking for conditions like that. -- Soap ^Talk/_{Contributions} 23:52, 31 January 2010 (UTC)

Yes, moving to a title that contains two or more consecutive exclamation points (or question marks, or interrobangs) is currently blacklisted (with the odd exception of four consecutive exclamation points being permitted). --Carnildo (talk) 01:08, 2 February 2010 (UTC)

So two exclamation points is forbidden. But four are not.—Ryūlóng (竜龙) 09:36, 4 February 2010 (UTC)

Trying to move article with title containing "(", ")" and "station".

I don't know which of those is blacklisted, but my guess is it might be any of these. Well, I want to move the page Stadhuis RandstadRail station to Stadhuis (Zoetermeer) RandstadRail station, because an article called Stadhuis (Rotterdam) RandstadRail station is also present. Actually, the latter one is a redirect to Stadhuis (Rotterdam Metro), but this is required for the RandstadRail station templates. The templates also explain the odd placement of "Zoetermeer" and "Rotterdam" in the required names, since those templates automatically add the phrase "RandstadRail station" to the very end of the article title, leaving me no choice but to use these slightly odd article names. Luckily, "Stadhuis" is the only affected station. Can someone perform this move for me, or change the blacklist so that I can do it? Thanks a lot, Bicycle bell 10:22, 18 February 2010 (UTC)

• Made the move for you. NawlinWiki (talk) 21:10, 18 February 2010 (UTC)

which matches the "termee" in "Zoetermeer". Apparently one of the letters in the first group is considered an alternate capitalization of the letter "t". --Carnildo (talk) 02:53, 19 February 2010 (UTC)

Can't we just get rid of most of these entries? I'm sure the edit filter does a much better job at this kind of thing (which didn't exist when these entries were created). --Conti|✉ 07:25, 19 February 2010 (UTC)

/Print subpages

Today I blocked the creation and editing of "/Print" subpages, since they are a security problem. They let anyone edit any template, no matter if the template is protected or not. As a test I used it to change the Wikipedia Main page, only using a non-admin account. It only affected printed versions of the main page, but that is bad enough.

/Print subpages also have a number of other problems. And we don't need such subpages, since we already have a better solution that has none of the problems. See Template talk:Documentation#/Print for the details.

--David Göthberg (talk) 10:57, 20 February 2010 (UTC)

NawlinWiki

Why isn't the word "NawlinWiki' (The name of an administrator who is attacked very often) in the blacklist? There is virtually no good reason that an article should have that in it's title... virtually every single instance is an attack page. The Thing // Talk // Contribs 17:02, 3 March 2010 (UTC)

To this I add the same question as above ... is it possible to make it name-space aware, or will all titles in all spaces with NawlinWiki in them be blacklisted? —Soap— 17:07, 3 March 2010 (UTC)

Sarey Savy

Looking at the title blacklist, it seems like all of the entries are used to prevent vandalism of various types. I have seen more than 20 attempts by a person named Sarey Savy to create a page about himself as a singer, going back to 2008, including Sarey Savy, Sarey savy, Savy Sarey, Sarey, Boy, Savy, Sarey Savvy, Sarey, Sarey (Singer), Sarey (singer), Sarey Savy (Singer), Sarey Savy (entertainer), Sarey Savy (Singer-Songwriter), Sarey Savy (Singer/Songwriter), and others on other Wikimedia projects such as Wikiversity. There was a discussion on the requested filters page where I wrote that a title blacklist entry would be better but was "unlikely to be granted". Well I'm here asking for it now, and I noted above that it seems to be entirely used for anti-vandalism entries right now rather than preventing continuously re-created articles. But perhaps there has never been an article that has been created and deleted quite as many times as this one. Would it be possible to add an entry? I note that Sarey and Savy are Cambodian names, and thus might someday appear in legitimate articles, but perhaps a message of some sort could be written directing people to a page where they would be able to get the problem fixed. Or is there only one message for all blacklist entries? —Soap— 03:25, 1 March 2010 (UTC)

Added one entry ... I note that he deliberately misspelled his own name in order to evade detection ... which would make it difficult for a blacklist, since I had always assumed he would at least want his name to be spelled right, but apparently this is not so. On the other hand, the variation between 'savy' and 'savvy' is trivial compared to the variations covered by the Hagger filters. —Soap— 15:48, 1 March 2010 (UTC)

You mean something like .*Sarey.* ? Ruslik_Zero 16:25, 1 March 2010 (UTC)

.*Sarey.* matches two existing page titles, which seems like an acceptably low false-positive rate. The problem is that if he's willing to misspell his own name to get an article in, then a blacklist entry is simply playing whack-a-mole -- he'll keep coming up with ways to get around it. --Carnildo (talk) 01:44, 2 March 2010 (UTC)

It's User:Channel 6 that is doing the creations, I might add. It's happening at Simple also. --Bsadowski1 01:46, 2 March 2010 (UTC)

He is unlikely to significantly misspell his name, otherwise nobody will recognize him. Slight misspelling is manageable. Ruslik_Zero 19:47, 2 March 2010 (UTC)

I don't really have any opinion on what the exact code should be ... .*Sarey.* (which I assume would disallow any page with Sarey in the title anywhere) would be good, though could it be made case-insensitive? But anyway I'm just interested in the principle of a disallow entry for a repeatedly recreated page, iresspective of what the actual code is. —Soap— 02:50, 3 March 2010 (UTC)

 Done Ruslik_Zero 11:58, 3 March 2010 (UTC)

Thanks. —Soap— 15:58, 3 March 2010 (UTC)

Hmm, I just thought of something ... does the blacklist support namespaces? I notice that the blacklisting seems to also prevent the creation of pages with Sarey in othername spaces as well, so there could never be, for example, "WP:Long term abuse/Sarey". Is it possible to get the blacklist to be namespace-aware or is it just a total blacklist? —Soap— 17:01, 3 March 2010 (UTC)

Blacklist does not support namespaces directly. It is only possible to use some complicated regex (with lookahead). If you want to create this page you can ask for WP:Account creator permission. Ruslik_Zero 17:28, 8 March 2010 (UTC)

Okay. Well I have no urgent need to start an LTA report about him, or any other page with his name in it, and if I ever do, hopefully I'll be an admin by then and if not I'm sure someone who is will help me. —Soap— 21:40, 8 March 2010 (UTC)

Latin + Greek

I've been trying to move Sarsasapogenin 3beta-glucosyltransferase to Sarsasapogenin 3β-glucosyltransferase, but the blacklist refuses move targets which mix Latin and non-Latin letters. Surely, given the frequency of such combinations in certain subject areas, the broad-brush blacklisting is overkill. Physchim62 (talk) 17:18, 8 March 2010 (UTC)

I moved this page. I have no particular opinion about regexes used to block Greek-Latin combinations, but such names are frequently created as a result of error or vandalism. Ruslik_Zero 17:35, 8 March 2010 (UTC)

censorship

need a debate on censorship here

clearly some things are necessary, but having looked at the list it sems there are censorship issues. like arabb unnittyy for example - a reasonable topic which has been written about both polemically and academically in print - not that i could contribute - well yes i can see that it redirects but that is a normal editting issue and if people want to write about "arabb unnityy" as distinct from "pan-arabism" or "arab unification" it is just like wanting to write about "educated" as well as "education" etc. etc., well sometimes editors will merge the articles but sometimes not, that depends on distinct content i suppose.

i'm not talking about the rude sex words

which need to be kept under control, not from my point of view because they are offensive but because the makers of certain websites seem to promote them with the most annoying net-clogging deceptive google bombing spamming etc etc techniques that just wastes space.

I am requesting help to move the page to its correct title. --Cerebellum (talk) 23:38, 27 April 2010 (UTC)

I suspect it's because it contains the phrase "an hero" (an Internet meme), and the filter it set up in such a way that it will trap a title containg that sequence anywhere in the title, but will only stop moves, not page creations (hence the creation of the page was not a problem).

Thanks, folks! I appreciate your help. --Cerebellum (talk) 13:41, 28 April 2010 (UTC)

Actually, the correct title should be G.I. Joe: A Real American Hero (Marvel Comics), which is the standard disambiguation per Wikipedia:Naming conventions (comics)#Between publications of different publishers. The article also needs to be added to the watchlist at Wikipedia:WikiProject G.I. Joe. Fortdj33 (talk) 22:13, 28 April 2010 (UTC)

Hmm, good point about the WikiProject watchlist, but I'm not sure how to do it. Any help? Also, I must admit to being confused about the comics naming conventions. I figured we needed "publication" on the end because, according to the page you linked,"If several comic book titles of the same name come from separate publishers, then default to publisher imprint: Starman (DC Comics publication) or Starman (Marvel Comics publication), for example." However, the "publication" doesn't seem to have too much of a purpose, so maybe you're right. Go ahead and move it if you want, but there are a few links you may need to update.

From what I remember, we usually don't put his stuff on the blacklist anymore, because he just resorts to using odd characters and such. I may be wrong though. The Thing // Talk // Contribs 23:26, 1 June 2010 (UTC)

There's still some Hagger entries on the list (e.g. the line about halfway down that begins with HНΉĤĦȞʰʱḢḤḦḨḪНҢӇӉΗἨἩἪἫἬἭἮἯῊЋΗ), but it seems a bit cut down from what it looked like last summer. I'd be slightly worried about false positives if we track Hermione, since it's a real name and could conceibably appear in a userspace article which is then later moved to mainspace, though I admit that would be very rare. —Soap— 23:42, 1 June 2010 (UTC)

The Ravishing of Lol Stein

Hi,
This is the English language title of a novel by Marguerite Duras which appears on a list of the 100 best books of the 20th century.
But it can't be used as an article title?
Huh? Whuzzup? Varlaam (talk) 16:24, 8 October 2010 (UTC)

Are you trying to move Le Ravissement de Lol V. Stein to The Ravishing of Lol Stein, i.e. move the currently existing article to a new title? You'd get a message like

"Le Ravissement de Lol V. Stein" cannot be moved to "The Ravishment of Lol Stein", because the title "The Ravishment of Lol Stein" is on the title blacklist. If you feel that this move is valid, please consider requesting the move first.

It would seem that it is disallowed to move a page to a title containing 'lol', even though it is allowed to create such a page. This presumably has to do with the fact that vandals in the past have often found it a lot more disruptive to rename existing articles than to create new ones which would just get deleted almost instantly. If you want the page moved, it's easy to do; if this is some other problem, please explain further. —Soap— 16:29, 8 October 2010 (UTC)

I did in fact do a move of the standard kind and was blocked by such a message.

Also some of the ones that I created were deleted as "test pages" anyway. I guess the blacklist isn't needed if the vandal isn't out there anymore (which I have no way of knowing, since it's difficult to search for deleted pages). —Soap— 00:37, 28 December 2010 (UTC)

Blacklist creating subpages of User:Example

User:Example is the example user, and the account name is used in various editing examples, apparently including advice somewhere about how to create a user subpage draft. While there are legitimate subpages of User:Example, very new editors sometimes create userspace drafts in that username's userspace rather than in their own userspace. I move or deletion-tag these when I find them, but it would be very useful just to blacklist the creation of pages starting with User:Example/, which would prevent these mistaken creations. I've made this request before and not gotten a response, but it looks like this page is active again; if there's a response this time I have some other requests of a similar character that I will make. — Gavia immer (talk) 05:40, 28 January 2011 (UTC)

Page moves

• The book Harry Potter and the Order of the Phoenix, which started this wave of page move vandalism, has been available for about ten and a half years and is no longer "the newest thing". Can we trust that the impulse for HAGGER move vandalism has died down enough? The extra regex-checking caused by need to check for such page titles adds to the load on Wikipedia's server, as other talk threads have said. Anthony Appleyard (talk) 10:26, 2 February 2011 (UTC)

It wasn't really that new when Grawp started it either (2007). And we've already pared back most of the Hagger filters ... compare what the page looked like two years ago to what it looks like today.

Please disallow the use of certain usernames in new article titles

I just looked at the edit filter log, and noticed that a vandal (who's now indef-blocked) had tripped the filter in the process of creating a blatantly abusive article with a really disgusting page title. With that said, I think it's time that the article title blacklist be updated to disallow the use of certain usernames in new article titles, as a new article that contains one or more such strings in its title is pretty much guaranteed to be a purely disruptive page. For instance, the string "NawlinWiki" should definitely be added to the title blacklist since that particular administrator has been taking a lot of abuse from vandals. --SoCalSuperEagle (talk) 20:54, 26 March 2011 (UTC)

I'm not sure why not to do this though. The user in question has left Wikipedia, and should he ever return, there is an ArbCom case that only was declined because he was gone, which is enough to make someone want to leave Wikipedia anyways.

I think we should add a regex to prevent users from creating pages starting with "Category:Category:". I finbd it hard to believe that anyone acting in good faith would purposely create such a page; such pages are always created by mistake, usually by new users who are subsequently confused about how to get thewm deleted.

Letter h

I removed the line

.*ͨh.* <newaccountonly>

which appears to block account creation for users with names including the letter h. If there's a good reason for this -- maybe this is just an h-lookalike -- it can be reinstated if needed, but due to the chance for serious disruption I thought it best to discuss here first.

CRGreathouse (t | c) 00:33, 7 September 2011 (UTC)

Can you please revert your actions? you obviously have no clue what that line does. It blocks accounts with ͨh which is a weird character and the letter H. not just the letter H. ΔT _{^{The only constant}} 00:38, 7 September 2011 (UTC)

If that's true, the only problem is that the edit was misplaced: it belongs under "OBSCURE ASCII CHARACTER LOOKALIKES". But I copied the symbol into my hex editor and it showed up as 0x68, "LATIN LETTER SMALL H". CRGreathouse (t | c) 00:41, 7 September 2011 (UTC)

I think you have it wrong, I see it has two characters I see ͨ <specifically 0x368 >and I also see h. the first looks like a weird C. Which is being abused in combination with the letter H. neither one of those characters are being forbidden totally, rather the combination which is a signature of a sockpuppet master. ΔT _{^{The only constant}} 00:45, 7 September 2011 (UTC)

What Δ said. Note that plenty of new accounts with "h" in them were created while this was part of the list. I'll put it back. NawlinWiki (talk) 00:47, 7 September 2011 (UTC)

Why do admins who have zero clue what they are talking about always stick their noses into things that they don't understand? Reverts of long standing administrators, and users who have far far more experience than you probably know what they are doing. If you had a question use the talk page, blind reverts/removals should not be an option. ΔT _{^{The only constant}} 00:50, 7 September 2011 (UTC)

(edit conflict) I'm definitely not getting that, but your description matches the codepoint: U+0368 COMBINING LATIN SMALL LETTER C. It's possible that this is one of the characters (like / and nonbreaking spaces) that give the page problems, but that seems unlikely. On the assumption that it doesn't cause problems for the page and doesn't block page creation with "h" (easy enough to test), it should be added back. You can count it as self-revert, but actually I'd prefer that you re-add it since I have concerns about my ability to add it properly (since I'm not seeing that character visually or through ghex2). Is it too much to ask you to put it in OBSCURE ASCII CHARACTER LOOKALIKES, whether with <newaccountonly> or without? CRGreathouse (t | c) 00:53, 7 September 2011 (UTC)

Thanks, you two. To answer your question, The only constant: because of the potential for massive disruption on the chance that it was what it appeared (given the evidence from my eyes and hex editor). I changed it and immediately notified the editor involved, as well as leaving a note here. CRGreathouse (t | c) 00:56, 7 September 2011 (UTC)

it actually shouldn't be placed in that section. because its not banning every use of that character, only cases where its followed by the letter H. That edit was live for about 5 hours. if it actually blocked what you thought there would have been bloody murder being screamed after about 5 minutes. Since there wasnt even a peep about this you where mistaken from the word go. ΔT _{^{The only constant}} 00:59, 7 September 2011 (UTC)

It's true, I was mistaken. I'm glad I left the messages I did! But I have seen disruptions caused by editors adding bad regexes to this page before, and it's hard to distinguish the two cases. CRGreathouse (t | c) 01:05, 7 September 2011 (UTC)

Why no "incompatible mixed scripts"

So "Fred" is acceptable and "弗雷德" is acceptable but "Fred 弗雷德" is not.

Is there a reason for this? I would understand banning non-English usernames because English people can't type them, but if you are going to allow other alphabets at all, how is mixing them any worse? If anything it's less confusing, because there is a recognizable English part.

This sort of name would be a good choice for someone wants to contribute to two Wikipedias with different languages, because then people on both projects would be able to recognize the username. Instead it is banned, why? 86.136.231.33 (talk) 18:03, 19 September 2011 (UTC)

Seemingly legitimate article triggering the blacklist

A new user apparently tried to create Wikipedia talk:Articles for creation/FEFCO ESBO Code, but it hits up against this blacklist. I discovered this when trying to move his userspace version (User:FEFCO/FEFCO ESBO Code) to AfC. There's a lot of regex going on here, and after a brief look I can't find the line that it is triggering. Anyone know which line this is triggering, and how we might be able to tweak it to allow this seemingly legitimate article? —SW— ^confer 17:16, 20 September 2011 (UTC)

Ok, I assume it's this one:

.*\p{Lu}(\P{L}*\p{Lu}){9}.* <casesensitive | moveonly>  # Disallows moves with more than nine consecutive capital letters

Any reason this is move only? I can create an article with 10 consecutive capital letters but I can't move an article to the same title? I don't know if it's worth changing it just for this article (which admittedly has little chance of succeeding to become a real article), but if anyone has any ideas feel free to shout them out. —SW— ^comment 22:14, 20 September 2011 (UTC)

The description on that one is a bit off: it's actually preventing article titles with nine or more consecutive characters that are not lowercase (your title has 12).

The character ư is listed under "OBSCURE ASCII CHARACTER LOOKALIKES" at MediaWiki:Titleblacklist. It should remain there. If you create the pages in userspace without that character then an admin can move them for you. Or you can create them at Muong Luan and Muong Loi and request a move, since these titles should probably redirect anyway - if they shouldn't be the actual titles in the English Wikipedia per WP:COMMONNAME or Wikipedia:Naming conventions (Vietnamese).

Some characters added to the Letterlike Symbols blacklist are Thai. They were added in [3] and one was removed in [4].

Chuvash letters "Ӑ" and "Ҫ"

Resolved

I think these letters are exclusive to names written in Cyrillic, not mixed script. Чăваш Ен and Чăваш Республики, the Chuvash names redirecting to Chuvashia, should be exempt from blacklisting, also Раççей, the Chuvash name for Russia. --IluvLovato123 (talk) 11:14, 3 January 2012 (UTC)

Those letters (Uncode code points U+4AA and U+4D0) are Cyrillic characters, and as such, won't be blocked by the mixed-script blacklist entries so long as they're only used in combination with other letters from the Cyrillic alphabet.

The problem you're running into with "Раççей" is that you're using "ç" (U+E7, the "c with cedilla" that shows up all the time in French) rather than "ҫ" (U+4AB, "Cyrillic small Es with descender"). With "Чăваш Ен" and "Чăваш Республики", you're using "ă" (U+107, "latin a with breve") rather than "ӑ" (U+4D1, "Cyrillic small letter A with breve"). --Carnildo (talk) 08:29, 4 January 2012 (UTC)

Second set of eyes, please?

Would someone please mind checking this edit? Don't want to screw things up here accidentally: [5] Thanks! Bob the WikipediaN ^{(talk • contribs)} 19:04, 13 January 2012 (UTC)

You didn't mark it as case-sensitive, so it would also block templates with capital letters. After that is fixed, it would fail to block something like "Template:Child taxa/aB", because your regex specifies that the end part must consist only of slash, comma, space, or lowercase letters. If (as your edit summary stated) you want to block anything that has a slash, comma, space, or lowercase letter immediately after "Template:Child taxa/" with no regard for what might come after that one illegal character, you'd want "[\/, a-z].*" instead.

Also, BTW, you may want to create a custom error message for this entry. To do that, create the message in the MediaWiki namespace (e.g. at MediaWiki:titleblacklist-custom-child-taxa) and then change the flags to reference it (e.g. change <casesensitive> to <casesensitive|errmsg=titleblacklist-custom-child-taxa>).

".*" is the standard regex notation for "any number of any type of character". There are other ways of expressing it, but that's the one everyone uses. "{.}" is not a valid expression. --Carnildo (talk) 01:35, 14 January 2012 (UTC)

Prefix:

Would it make sense to add " prefix:" to the title blacklist? Many pages on Wikipedia allow the reader to search the archives, and generate search results like this, which almost seem to direct the reader to click on the red link, which they sometimes do. 28bytes (talk) 20:48, 14 March 2012 (UTC)

It's a good idea, I just wish we could customize it to say why the title was disallowed. Some people might just see the red "Unauthorized" box and not know why and then give up. ☮Soap☮ 22:22, 14 March 2012 (UTC)

Oh, I was thinking adding it to the blacklist would prevent the red link from showing up on the search page in the first place; is that not correct? 28bytes (talk) 22:24, 14 March 2012 (UTC)

Apparently typing a blacklisted title does modify the text to "you can ask for it to be created", something I had never realized. I guess I don't really have any objection to the addition though I'll hold off adding it myself since I'm not sure how to add it properly. It still would be nice if we could get the software to just remove the prefix: thing entirely but I imagine that could only be done by the developers. ☮Soap☮ 23:00, 14 March 2012 (UTC)

This line prevents these vandals from doing so via regular expressions code. .*Bsadowski1.* in the code, with the periods and the asterisks, basically just means that anyone who registers a user name with "Bsadowski1" in it will get rejected, like "Bsadowski1 is [INSERT INSULT HERE]".

Pseudo-IPv6 usernames

See e.g. 1, 2. It seems that some users are capitalising on the current lack of familiarity with the new IPv6 system (and consequent hesitancy about blocking – see e.g. 3) to create pseudo-IPv6 usernames. The only explicit guideline I can find on the issue is WP:UNCONF, but there seems to be general consensus (from e.g. discussion 1) that these sorts of thing are against the rules. Therefore could someone who knows REGEX far better than I do create a new rule preventing non-Account-creators from making such usernames? Thanks. It Is Me Here ^{t / c} 20:17, 24 June 2012 (UTC)

Such usernames are clearly against WP:U#Misleading - "usernames which resemble IP addresses". KTC (talk) 20:42, 24 June 2012 (UTC)

You're a little late for at least one variety of IPv6-lookalike names. You'll have to be more specific if there are more types you want to blacklist. Anomie⚔ 00:38, 25 June 2012 (UTC)

I'd suggest blocking the creation of any username with four or more colons or colon-character lookalikes in it. -- The Anome (talk) 00:45, 25 June 2012 (UTC)

Again, please excuse my ignorance of the code, but will the current rule only block names that look exactly like an IPv6 address, but that just happen not to be one, or will it also filter ones that look like one to humans, but are not formally of the IPv6 form? Again, I direct you to diff 2, where the user's username could not be an IPv6 address since it had the wrong number of characters between the colons, not that this makes the name any less misleading to human editors. I am just concerned that such names may be able to slip past automatic filters? It Is Me Here ^{t / c} 11:15, 25 June 2012 (UTC)

As far as I'm aware, the software itself now forbids usernames that are valid IPv6 addresses, so that shouldn't be a problem. The problem we should be addressing is names that look like v6 addresses, but aren't. For example, "2001:0:700:fab3:10ef:49sf:22fe:94e2" and "2001:700:fab3:10ef:49af:22fe:94e2" both look very much like, but are not, valid IPv6 address strings. They should both be blocked, for the same reason as names like "193.201.355.26". -- The Anome (talk) 11:48, 25 June 2012 (UTC)

Moreover: "2001::700:fab3:10ef:49sf:22fe:94e2" is a valid IPv6 address string according to the RFCs, but would not be generated by the Mediawiki software, which does not use the "::" abbreviation. We should ban it too. -- The Anome (talk) 11:59, 25 June 2012 (UTC)

(edit conflict) In that example, 200:0DB8:0016:0005:0ACE:0BD1:07BE is described as invalid, which is true: but for the wrong reasons. The reason that it's invalid is that it's got the wrong number of groups - there are seven, but there should be eight. The stuff about "should be 4 digits:1 digit:4 digits at the start - this is 3 digits:no digits:4 digits" doesn't hold true, since any group can have up to four digits, since leading zeros may be omitted. That is, 0200 and 200 are the same, see IPv6#Address format.

The problems that I see are that unless a user encountering such a sequence of characters is familiar with the rules, they won't necessarily be able to distinguish a good IPv6 from one that's a deliberately-crafted fake. For example, a username like User:2001:gdb8:85a3:0000:0000:8a2e:0370:7334 cannot be an IPv6 address, because although it's got eight groups of four, the second group includes the letter g, which is invalid hexadecimal. On the other hand, 2001:db8:85a3::8a2e:370:7334 may appear to be invalid, but is in fact valid, because all leading zeros may be omitted, and the sequence :0000:0000: may be reduced to ::.

The Anome's suggestion of 00:45, 25 June 2012 sounds fine; we could even set the limit lower. How many genuine usernames will require more than one colon in addition to the namespace separator? --Redrose64 (talk) 12:09, 25 June 2012 (UTC)

I am not User:The Anome. I hope you don't mind I fixed that for you ;) Anomie⚔ 15:34, 25 June 2012 (UTC)

Sorry! --Redrose64 (talk) 15:44, 25 June 2012 (UTC)

Regarding the question of how many usernames will require any number of colons, it might be a good idea to get someone to run a query on the toolserver for usernames with multiple colons (or colon-lookalike characters) and post the list somewhere for us to examine. Anomie⚔ 15:49, 25 June 2012 (UTC)

The MediaWiki software should currently be blocking any username that is a syntactically valid IPv6 address, including addresses like "2001::700:fab3:10ef:49f:22fe:94e2" that are valid but not in the format MediaWiki normalizes to.

The current blacklist entry will in addition block creation of pretty much any username that consists of characters 0-9, a-f, A-f, and colons (where the groups of non-colons are up to 10 characters long). The current blacklist entry will not block names such as "2001:gdb8:85a3:0000:0000:8a2e:0370:7334" that include other characters (e.g. 'g' in this case). Anomie⚔ 15:39, 25 June 2012 (UTC)

To prevent this being got around with character spoofing, here's a quick list of Unicode characters that look like colons:

U+003A  COLON
U+003B  SEMICOLON
U+02D0  MODIFIER LETTER TRIANGULAR COLON
U+0589  ARMENIAN FULL STOP
U+05C3  HEBREW PUNCTUATION SOF PASUQ
U+0703  SYRIAC SUPRALINEAR COLON
U+0704  SYRIAC SUBLINEAR COLON
U+2236  RATIO
U+A789  MODIFIER LETTER COLON
U+FE14  PRESENTATION FORM FOR VERTICAL SEMICOLON

so a suitable regexp for, say, matching three colon-like characters in the same name might look something like:

.*(?:[<colon-like>][^<colon-like>]*){2}[<colon-like>].*

or even (provided it does not cause pathological behavior in the regexp matcher), the equivalent

.*(?:[<colon-like>].*){3}
