I often wonder what can be done about bullying. You're never going to get rid of it entirely. Again, sometimes the only thing you can do is get out of the situation (go to a different website, go to another school, etc.).
When I was being bullied as a child, one thing that sticks out to me was out checked out the adults were. Either they were completely unaware of the bullying, or they actually participated in it themselves not realizing how much damage it was causing. Here's the thing, most of us are bullied at least once as children. But then we grow up and we look at children and think "Aww, how cute!" forgetting how asocial and cruel children can be.
