You can set your Myspace profile to private (or my friends only) so that only your friends can view it.
This is a way to keep someone from finding to much out about you or your children. Like we have discussed before it is a good idea for the parent to have a Myspace account and become friends with your child and their friends.

Steps to set your profile to private:

• Log in to your Myspace account
• From your HOME page, select Account Settings
• Next to Privacy Settings, click Change Settings
• Where it says Profile viewable by click My Friends Only
• Press the Save Changes button

That's it! Now only people on your friends list will be able to view your profile!
