(under construction) After editing fringe science articles for several months, I've come to the observation that single purpose accounts cause nearly all the:
- Inaccurate information
- Edit wars
- Article degradation
- Article instability
- Wasted time of good editors
in fringe topics and biographies. What worse, they drive away and tire out highly valued impartial and expert editors. (mountains of diffs to follow once I've established compiling this isn't an attack on users)
I believe that a procedure for blocking them, where their SPA status is taken into account, would greatly help Wikipedia deal with many of its problems in these areas, while doing little harm if implemented well.
It would be similar to 3RR, with a few more protections. An example of a possible policy:
1) An SPA is defined as a user whose article edit count is greater than 10; has more than 50% of their edits on a particular article or a few very closely related articles; and has more than 10 edits to these articles.
2) If three editors in good standing request that an SPA be reviewed, and an uninvolved administrator agrees that there is evidence of edits against consensus, the SPA will be blocked for 24 hours.
3) Blocks escalate each time, leading up to a topic ban for that user. If they wish to contribute to the encyclopedia, they are free to edit the rest of Wikipedia's 2 million + articles.
