Schools - Do nothing. It doesn't have anything to do with them. They need no more participation in it than they need participation in what happens after school between two kids on a playground. The school's role is education, not policing the activities of children off school grounds. At most, they should educate children (reasonably) about the dangers of stuff online. No, I don't mean scaring them about predators, but informing them that (unfortunately) people, jobs and police can and will use what you say online against you. As you say, this isn't their diary. Parents - They should parent. In the modern times that means educating children about the internet and expected behavior online. Teach your kids about privacy settings. If needed, regulate access to digital devices. I'm sure (most) 13 year olds aren't buying their own cell phones, computers and internet access. Kids are rough on each other, but they've always been rough on each other. The only difference now is that its a larger audience and more to interact with. Kids need to know that they can simply 'opt out' if they want to and stuff gets too socially complex. They don't need to have a Facebook profile that's 100% public to every other kid in school. They could have a very locked and and private profile, or no profile at all.
