b!z once filled all the first page of the off topic and nothing happened to him. There is a thread about it somewhere here in meta.
Wrong. He was temp banned if I recall correctly.
Maybe the problem is allow such threads in first place?
No, the problem is we allow users like you and your alts to make shitposts all over the forum for far too long and without repercussions. You should have been banned when you got caught cheating your campaign a while back.
