I believe that as a parent we must insist on being in full control of our childrens computer use. difficult child or easy child it makes no difference. There is a few different programs that you can get that will moniter every keystroke made, without anyone but you even knowing it's there.
Just recently a little girl (11 years old) my difficult child used to go to school with started calling him and asking for his e-mail address. difficult child doesn't have an e-mail address so he gave her mine. I couldn't believe the pictures she sent! She sent five different pictures of herself in a bikini top or a skimpy camisole, as well she was holding her chest area and making kissy lips. I phoned her mother as soon as I saw that, and the sad thing was she didn't sound near as concerned as she should be. This girl is allowed to have a computer in her room, as well as her own unmonitered e-mail address. Scares me to death
