The humorous Peter Griffin mistake notwithstanding, any new evidence isn't relevant because a new ban isn't relevant. The question isn't whether to ban him or not, its to pardon him or not. He's already banned and KY made it clear he is asking for the existing ban(s) to be enforced. This is a legitimate grievance supported by forum rules and can not honestly be described as trolling. The only reason Tank is posting now is a sort of unofficial, self-served, pseudo probation born of his creating a new account.
I am indifferent as to whether Tank is pardoned or not. And as unpopular of an opinion as it might be I like you although I think you're being unfair to KY for what's effectively expediting a decision on Tank's most recent incarnation.
