Site-locking?

[Jacob_Miller]

I've made several games, and one of them was stolen and uploaded on various sites. I was wondering how to make it so that unless my game is played on a specific website (Kongregate.com) the game won't work.
I also have heard that a sitelock can be bypassed by hosting the game through the original site, so something to prevent this from happening would be good too.
It would also be great if this was simple, because I don't know a lot about this sort of stuff. It's still more important for it to be successful than easy to program though.

Thanks, this is really important to me!
