He was a gimmick account who posted normally but invariably would ask somebody for an alibi if they ever brought up a personal story that didn't involve the speaker. He just stopped posting one day, but I'll never forget that man who had no affiliation with the federal bureau of investigation.
The Fightin' Manboobs - Always gave me a chuckle, both as to user name and content posted.
SuicidalMarchingBand - Oddly, was not a 14 y/o edgelord.

I think he was allowed to change his name to something less offensive and not banned outright. But, alas, the magic was lost.
