Hacking/Password Finder, I need one. Options

[Knight]

I did a search on Google and found nothing. There's just been a boost in the popularity of my site and I'm afraid there's going to be jockers. I don't plan to sabotage Jocker Xangas, just take out what they've stolen from me. My cousin, for instance, is a huge jocker. He steals ideas and pictures from me and I get absolutely no credit (and it uses up my bandwidth). I know his password and he doesn't know about HTML. But then there's the serious jockers. The people that steal everything. That's what I'm worried about. HELP!!!

EDIT: Jockers are getting smarter every day. I can't simply change the links. They upload it onto their own servers. Though illmizzkim's idea is a creteive one. Maybe I'll do that if someone is stupid enough to do that. I'll change the url to a phto of this naked guy so they get blocked from Xanga . Do not reply unless you know how to hack or know about a password finder.
