My 2 little angels are only 7 and 8, but i'm never gonna allow them to chat to people on the net unless i'm with them so they don't get targeted by paedophiles or harrassed by men wanting to get them in bed. Any man tries anything like that and i'll message them back saying "do you wanna meet me", so they think it's my daughters, then meet them and kick them a beating.

The net is tooooo dangerous for children, full stop. 18 is the safe age I suppose. People ignore a lot of the time how dangerous the internet is.
