I hate it when kids get cyber bullied, it's one of the worst sights you have to witness. I and my peers stick up for the kid that is getting cyber-bullied because that is the ethical thing to do, we don't care if other peers tease us about it. Human life is sacred, no matter the individual.
I believe the parents need to restrict web browsing until they believe their kids are mature enough for it. I've never cared about bullying, I don't understand it, but whatever.
Kids have always been bullied, as a kid you have to experience the harassment. It prepares you for the future.
