I read a couple of responses to this that went along the lines of "that will never happen because of..."anonymity" or its a place to "bitch and complain", etc. You're missing the point, in my opinion.
Many online gaming communities are very hospitable despite complete anonymity, etc.
I think the problem lies in the fact that Demigod, on its face value is an easy game to get into, and so you will find many more younger players than you would in, say, the sins forums. I'm not saying that younger means more immature all the time. I'm sure we have some very young, very mature young kids out there, perhaps reading this right now. However, over all, more youth=more school yard mentality.
In general, the more complex a game is, the more mature its forum users.......Eve Online not withstanding
