I wouldn't call it overmoderation, I'd call it
selective moderation. Moderators have admitted that they can only moderate threads where there is a complaint or that they themselves read. On several occasions, I've observed threads that were particularly 'flame-y' that were allowed to go on until certain people were the target of said flaming (which allows me to infer that the thread was moderated only after it was reported, which moderators have admitted happens). It also seems that some are allowed to flame openly, and others are not.
My post above wasn't directed at you; I haven't received threats of bannination or warnings from you, that I know of. It's meant to give you and the other moderators something to talk about in the moderator forum (see, I'm helping you by increasing traffic in that area).
