Interesting case with the question Regex to remove certain patterns from urls .
The user who asked this was recently registered. The profile is empty and this is their first question.
Then there is an edit https://serverfault.com/review/suggested-edits/520382 which is coming from "anonymous". This edit does not just improve the question with better formatting, grammar/language, fixing links, or even moving info from comments, but it provides some additional information.
This must be the same user who forgot to authenticate? Or this could be the vandalism, somebody tries to divert an attention and prevent the original user to receive valid answers?
Should I accept edits in such cases?
