I'm a Bengals fan. So I know about haters. They boards there are actually very lively so they have tons of moderators and the moderation is heavy.
It is like the opposite of this place. They merge threads if two topics are even remotely close to one another, which create these mega-threads where you can't even tell what is going on because it is three or four threads mashed into one. They also strictly police cursing, knocking the moderators, other teams' fans being in Bengals-only forums, but strangely let personal attacks go. It's pretty bad and I got tired of the place.
