I'm not one for heavy handed rules but when sometimes you have to create a culture by enforcing some simple rules. A few more moderators would help make sure this happens. Banning some users would simply benefit this forum and make it better. I say create a sub-forum called "teh kiddies can insult each other in herezzz" which is completely unmoderated and then heavily mod the rest of the forums in order to maintain a high quality level.
