Dynamite post, Hun!
I still think you need Hun phone sex lines though
Krome, why don't you just email him about the offending content... Isn't it possible that some of your actual customers are posting their purchased images on Hun's site despite the fact that your license agreement might preclude it? If so, go after those guys... or the hosts where the pictures are... You could definately do that. Find a local scumbag attorney that's wants alot of volume on a contingency and sue everyone that has your content illegally.
