From Psychology Today: Internet Trolls Are Narcissists, Psychopaths, and Sadists (h/t to John Goetz)

[NOTE: I've always believed that people who taunt others while hiding behind fake names aren't really contributing anything except their own bile and hatred. The two people that came to mind when I read this article were Dr. Joshua Halpern of Howard University aka "Eli Rabett" and Miriam O'Brien aka Sou Bundanga/Hotwhopper. These people are supposed to be professionals, yet they position themselves as childish cowards, spewing invective from the safety of anonymity while taunting people who have the integrity and courage to put their real names to their words. The best way to combat people like this is to call them out by their name every time they practice their dark art. To that end, and not just for these two losers, I'm stepping up moderation on WUWT. If you want to rant/spew from the comfort of anonymity, find someplace else to do it, because quite frankly I'm in a position in my life where I don't have the time to deal with this sort of juvenile crap. Be on your best behavior, otherwise its the bit bucket for you. Moderators, take note.. - Anthony]
