Problem is that some of the "Tube Site" are foreign owned. How do you go after them.

As long as their are fetishes of all kinds there will be porn whether it's pirated or not. There are freaks out there who would just make their own amatuer porn and just post it to get their rocks off. I don't see porn going anywhere except bigger and better. The Hotels sell tons of porn on Pay per View. Heck the Mormons won't take it off of the Marriott hotels pay per view.
