Would you / have you allowed your tweenager (10-12 yr) to have their own Facebook account?

I would allow my child to have one. He actually has one at this moment, But i monitor it on a daily basis. My child was told if i see something that i dont like it will be gone.  Now days  i think parents need to be up front with there kids. Kids now days are nothing like i was when i was growing up they seem to be more advanced in certain things. So thats my modo if your up front with them they are most likely to be up front with you.
