To be honest, Dan, I think you'll get that on either side. 15k players on each side per server (i think that'll be about right), you're gonna get a number of complete asshats in the same vein judged purely by the laws of probability. And not just kids either. Half of em will be 30+
I've never used general chat in games anyway so usually just ignore it. If anything, it's a decent tool to judge what...erm...tools never to group with.
