Any website kid/teens shouldn't be aloud on?

[veryberry21]

Just curious to see how many of you havebanned your kids/pre-teens/teen from going of certain websites. Any websites you don't allow them to go on?
(This is purely to satisfy curiosity)

formspring.

It's a place where teenagers abuse each other anonymously, I'm not sure why it's still going especially now that they've closed down littlegossip which was essentially the same thing.

Facebook.

I work in a school, if I had a quid for every time we had to sort out an issue started on there, I'd be sunning myself on a yacht in the carribbean & wouldn't need to work.

Cyber bullying? It's even played a part in a murder recently where I live. Wouldn't let any child of mine on it, at all. I also know of people they've lost their families through it, and worse.
