A user called GXS has done a substantial rewrite of SCP-090, claiming to be its original author. Frankly, they've ruined it; the new version is sloppy and the tone is atrocious.
SCP-090's author is listed as far2, meaning that it was ported from the old site and the original author is unknown. This means that GXS' claim to be the original creator is dubious at best. Further, the article had undergone a hefty rewrite by another author, Agent Circeus, which had brought it into the positives.
So.
The question here is:
Does GSX have a right to do a rewrite on this article without staff approval? Is there even a way to prove they wrote it at all?
I believe that following their rewrite, the article should fall under the purview of Circeus, and that the page should be reverted. Users have already begun to post in the discussion thread that the rewrite has detracted from the article.
