I can read my difficult child's myspace because I know her password. I got her password by checking "forgot my password" and they emailed it to her. Since I know her email account password I just went in and got the myspace password and then deleted the email.
Invest in a monitoring program that not only lets you monitor everything typed but also records all passwords typed in. I had to be very vigilant about the computer use several years ago and thankfully she is now outgrowing much of the foolishness she use to engage in with the computer, but I still monitor it to make sure she is OK.
I've talked to a lot of parents who have no idea what their kids are doing on the computer. I know a lot more of what they are doing then their own parents. My difficult child use to run away and I had to know who she was talking to so I could find her. I broke up several drug parties because of what I learned on the computer.
You may be able to contact myspace and ask them to give you your difficult child's password. They have added a whole new department to monitor problems and try to keep kids safe and to respond to growing criticism and life threatening situations. They may have a procedure for this now. I've contacted them several times in the past and asked them to delete my difficult child's myspace accounts because of misuse. They are much more responsive to parents concerns lately.
