You may actually be surprised at how few people are banned from the entire forum (as opposed to banned from specific threads), when you consider the antagonistic approach of some on here. Generally speaking, bans are seen as the last resort, and are not handed out willy nilly. We will generally discuss any action being considered, and if there's a consensus, we'll go with it. Speaking for myself, I don't remember handing out a single ban that I hadn't discussed with the other mods. Even warnings are only occasionally issued. Speaking personally, I will usually post in the thread asking people to calm down and, if there's an ongoing "difference of opinion" with another poster, to either put that poster on ignore, or take the argument to pms.
@Ric is very keen to avoid the heavy handed modding seen on the likes of RAWK, he prefers the softly softly approach, and prefers the forum to "self mod" if at all possible.
