breaking rules. If they lightened up and weren't so subjective they might be able to handle posts that actually break the rules or should be moderated.
I personally haven't had too many run ins with the mods fortunately but my few experience and others I have witnessed or heard seems to suggest they make way more work for themselves than they need to or should.
I don't agree with the no suspension at all idea. I think it is appropriate from time to time especially for severe stuff. I just think the moderation is usually aimed at trivial innocent stuff rather than anything that makes the board better.
