User ruffle5 recently posted an article to the mainsite that went into deletion, was improperly deleted by the author, then properly deleted by staff. (http://scp-wiki.wikidot.com/forum/t-13891349/deletions-70:if-the-fact-will-not-fit-the-theory-let-the-the#post-4833790).
While this was happening, the user also sent an exceptionally vehement PM to a member of staff:
The user then proceeded to try and walk back the vehemence by claiming that they were responding to someone else who told them that their work sucked and they should get off the site, but were unable to remember who it was or provide screenshots as they "deleted them [the PM] in a rage".
Regardless, engaging in this level of vehemence is unnecessary and violates Rule 0.
Recommending revoke.
