retagging to feature requiest as there is interest.
Before I got a chance to reject it the edit was already approved by three other reviewers. As there's no way that I'm aware of to contact the original editor or reviews to attempt to remedy this behavior, I simply made my own edit to the wiki to add a source for the content.
Now it occurred to me that if this editor was updating wiki's with plagiarized content, this might not be the only time it was done. Ideally I'd like to search for all wiki edits done by this user. (and in general terms by userxxxxx).
Given this situation I'd really like to see a new feature on SO that would allow us to search for all instances of a user's wiki edits. This could be as simple as going to the profile->edits page for a user and just adding a sort item for wiki's vs. questions, vs. answers
For those not aware, when one is reviewing edits, the reason listed on top for an edit to be rejected is because of plagiarized content:
