Yeah, that's pretty bad--and so is the rest of OP's post, which I confess I did not finish reading.  And you're right, ChiBitCTy got un-banned and there may be one or two members over the years who've gotten their permaban reversed.  It's so rare that I can't remember the names of members or if there's even more than one. 

OP, you basically have to be an extremely valuable member of the forum (and having a lot of support from the community like ChiBitCTy did doesn't hurt, either) to get a permaban overturned.  If you're a lower-ranked member who's plagiarized something and start an appeal thread in Meta in which you make excuses and beg for forgiveness, it just falls on deaf ears.  Invariably.

That's the way it should be IMO.  It's just too bad scammers aren't permabanned.
