this is unfair ,just another case of bored kids looking to take out their misery on others.
a similar thing happened in a school near me
there was a young teacher that was shy and suffered from bulemia or something and one stage and she was bullyed in the school and through bebo. I think things have to be rethought in education for kids so they are not drawn to this sort of behaviour.

Question is, where are the parents? I mean don't they monitor the bullies computer use?

A lot of them are bullies themselves.

I see, then its one of those cases where the parents should pay for their children's sins and maybe that way they do a little more disciplining and less consenting

Exactly. The parents who are trying to protect their children from the bullies are often bullied by the parents who condone what their bullying children are doing. I've seen enough of that to know the truth. When I was growing up, the parents were responsible for their children's actions. Most of the time that was enough to keep the children from harming others or vandalism, etc.

I would not put up with the bullying. You come after my kid and there will be HELL TO PAY! And if I caught my kids doing it, they would know that they are wrong and I will not allow it. I think that people put up with to much crap from cowards like these, confront them and shut them down, bullies, no matter the age, are cowards and once you stand up to them they deflate quickly.
