I couldn't agree more
I agree also, my 13 year old has an account but it goes through my email address and if I feel the need to check the messages etc I can. Well, I felt the need recently and while I felt uneasy invading her privacy, I also knew I was going to find something I didnt want too .
My instincts proved right and after grounding her, confiscating her Blackberry (cos BBM is as bad!!) and deactivating her FB account, I can safely say she wont be allowed to sign up till she is 18!!!!!! Shocking!!!!
