I like the truth in advertising thing you've got going on there.
I wasn't thinking so much about evilness for entertainment's sake, although that certainly has a place on GreekChat.
It was more people like Macallen25. He doesn't (seem to) worry about it being PC; he doesn't (seem to) worry about people concluding he has a lot of personal experience with risk management issues. He doesn't (seem to) worry that he will seem mean or ungentlemanly: if he hopes that you get killed by killer bees, he just posts it.
I guess posting with impunity is partially why people create sock puppets, but I sometimes admire the folks who put it all out under one user name.
