Psychological profile of the internet troll

In light of all the attention-seeking, cut-and-paste, intended-to-offend junk being posted recently, I thought some of you might find this amusing.

Psychological profile of an internet troll from a Stanford study

'Trolls are typically anti-social and often depressed or less often just ADHD. Think of them as the kid who acts up in class, making disruptive jokes, or other people who do bad things to get attention. They typically have problems at home or just in their general social life. The depressed or ADHD ones are often doing it to try to "feel" something. Since normal life isn't causing them to feel normal emotions they try doing things outside of the norm. '

But don't worry trolls, some medication and therapy can help.
