Things like faceboook for kids under 13?

Not as far as I know! You have to be 13 or older- no younger. If you are under 13 and get a Facebook account and the owners find out, they can fine you. That's 's what I've heard. My friend's little sister is 10 and she got Facebook, she was banned for life on it. So I don't think you should get Facebook if you are under 13. Hope this helps.
