If the abuse is as bad as OP says (and I've no reason to doubt him), then FH's duty is to nuke what appear to be spam threads. That's what OP's complaint seems to fall under. If you're creating enough threads such that most of them make up the first page of any section....that sounds pretty spammy to me. Sure, people are going to complain that it's not rule-breaking, that it's a matter of political opinion, but that doesn't sound like reality to me.
With all that said, I don't think B1tUnl0ck3r needs any new rules... just trash the "zero or low value, pointless or uninteresting posts or threads" and keep trashing any new ones with "pedo" in them until he gets the message. He can have one megapedothread and that would be enough.
