Trolls live under bridges and on the internet. Social media websites and forums are overrun with users who create fake accounts just to stir up trouble. These people make racist or out-of-this-world comments, as a way to rile others up. Normal users typically fall for this technique and windup raising their blood pressure arguing with them. So why do these internet trolls rile people up? It's perhaps because they didn't get enough hugs when they were young.
