May 2018 edit
Please do not add promotional material to Wikipedia, as you did to Orders of magnitude (length). While objective prose about beliefs, organisations, people, products or services is acceptable, Wikipedia is not intended to be a vehicle for soapboxing, advertising or promotion. Thank you.

You may be blocked from editing without further warning the next time you insert a spam link, as you did at Chetan Sharma. Persistent spammers may have their websites blacklisted, preventing anyone from linking to them from all Wikimedia sites as well as potentially being penalized by search engines.

You have been blocked indefinitely from editing for advertising or promotion. From your contributions, this seems to be your only purpose.
If you think there are good reasons for being unblocked, please read the guide to appealing blocks, then add the following text below the block notice on your talk page:
{{unblock|reason=Your reason here ~~~~}}. Widr (talk) 18:19, 23 May 2018 (UTC)
