They're just the same on MSN.

I don't class it as bullying though. They were more just annoying me. e.g. I can hardly report someone for bullying me at school just because they walked past me and called me a twat.

Even if they were doing this 'cyber-bullying' to me, or anyone else for that matter, the best way to stop it is to stop using the service. If you don't have a MySpace profile or an MSN address, they can't bully you with it.

On MSN, as soon as I blocked all the people that were being silly, they stopped. In fact, I have been even less annoyed by MSN since I stopped using it regulaly.
