At that point I think it would be totally ok to report him off to the GMs. There is really no need to take this bs, especially if they are telling people to kill themselves and the like, and I know that the GMs might not do much yet what with RMT, but still, there is no reason they can't just toss jerks into game-jail for a day and keep them out of DF. :/

With any luck, the assholeish ones will soon be gone, as soon as their 30 is up. I've been moderately lucky and only encountered one ass on a alt (lol) character, but it's really bad that we as players even have to put up with it.
