Cyberbullying

This is a threat to your kid. Some other kids with access to a computer and an internet connection may spread rumors and bad stuff about your kid. This might potentially lead to suicides, depression, bad performance at school, beatings. I would highly recommend parents to supervise whatever their kids do in the web because they may be or putting someone else in danger.
