Why hurt others?

The article, What Happened When I confronted My Cruellest Troll by  Lindy West.  It talks about how she was harassed by an internet troll and also how Zelda Williams was harassed by one also.  After the passing of her father Robin Williams, she was harassed by an anonymous troll, he used a fake account on twitter to harass her, and what hurt her the most was that the person that was trolling her had put a picture of her father so it looked like if he was the one typing the most horrible things to her.  Some people are against the fact of being anonymous online and some people are fore being anonymous online.  There are certain things that are reasonable or understandable, like if someone donated an organ or gave blood.  They have the right to keep their identity anonymous, because they don’t want their information getting into the wrong hands.  I am fore people being anonymous, because there are certain things that you want to keep private, and also some people don’t want their business out in the open where everybody can see.
