I'm so sick of hearing of cyberbullying and then posting online! What do you think should be done to deter it?

We live in a society that prides itself on freedom of speech. I know there are those who think laws should be made to make this a crime. However, you can also make the argument that no one makes another person log on to a specific site ( such as MySpace) and e-mails from senders can easily be blocked. It's sort of like if someone is bullying you when you visit their house - you stop going there. I DO think laws should be enforced when it cease to be bullying and becomes threatening.
