I'm pretty sure Unsung was banned for saying something negative about the tribe. Can't remember exactly but I bet it had something to do with "racism". But here's the thing, how come Ron tolerates Alex's frequent antisemitic (and other racist comments) comments? How come he's even given a forum section? Aaron Singerman doesn't seem to get offended by Unsung's comments, and he's a tribe member of course.
Just let the guy back... one of the best posters ever.
