Hello. I’ve made a game for viceland, and as always when you make a good game, lousy free-game-portals plain steals it and puts it on their site.

So now i’m trying to take a few actions to prevent this from happening. One thing is that i’d like the swf to check which domain it’s being viewed on.

I thought you could check which domain the html/php is on somewhere using SYSTEM.SECURITY or something. But i don’t find any.

Any ideas?  
I’d be very glad for any help.  
And heres the game if you like to play:
