What users should to do with users that violated that rules (if the is are rules)? Report to moderator? Report to Reputation board? Something other?
I don't know what you're talking about so publicizing it would be a good start. 
Write a thread directed at theymos. It's effectively a semi-centralized of the original DefaultTrust - he blacklists some users but doesn't pick and choose directly.
OK. I have created a new topic for this.
