n this month's issue of Personality and Individual Differences, a study was published (link is external) that confirms what we all suspected: Internet trolls are horrible people.
Let's start by getting our definitions straight: An Internet troll is someone who comes into a discussion and posts comments designed to upset or disrupt the conversation. Often, in fact, it seems like there is no real purpose behind their comments except to upset everyone else involved. Trolls will lie, exaggerate, and offend to get a response.
