Conventional wisdom says that the anonymity of the Internet lets people behave in ways they never would in real life, or online if their identity was known. But, if you think that means that trolls are normally nice people who only act out in their online persona, think again. New research shows that internet trolls are, in real life, narcissists, psychopaths, and sadists.

Not surprising...

As for the anonymity thing... yeah, its definitely a double edged sword. On the one side you have better privacy which is important to a lot of people and communities alike which gets rid of the aspect of getting judged for the things you post, discuss or create. On the other hand it lets trolls run amok because they too are protected by the very thing that frees people to do what they truly enjoy. I guess the question is, "Where do you draw the line, and when?".
