Science confirms: Internet trolls are terrible people (opens in new tab)

To me the fact that "trolling" means different things to different people should be enough to render questions on it moot. What I call trolling is playing devils advocate and taking extreme counter-positions to make someone "bite", and isn't really harassment or bullying.

But it's a fine line, and in the end you have to decide whether you're ok under free speech with someone taking the "Hitler was a net positive" position [on a Jewish dating site] or if that's a form of harassment.

It's interesting that only introverts waste time using computers, phones, and other devices to access networked communication methods. Quite astonishing that everyone I see online is an introvert. Extroverts have no use for these things, instead going outside and never touching anything electronic. When writing letters was more popular it was probably only ever done by introverts too. An extrovert, as a personality type, is far less likely to use every form of communication possible, instead relying on only face to face, real life dialog for their needs to tell other people what is going on in their heads.
