Hate to bring up this again but:
Disable your vCard.
It displays whatever e-mail you registered with. That's how Leopold was able to find that kids MySpace. It's really no secret, he wasn't doing anything the cops haven't all done already, it's old news.
USER CP(top left) => EDIT OPTIONS => UNCHECK "Allow vCard Download"
I still see a lot of users with this enabled, and it takes seconds to find your MySpace/Facebook with it. Fix it.
