But it seems like they're doing their best right now to keep Pirate Bay on the run. Each time they move, pressure gets brought to bear to make them move again. Sooner or later they're going to run out of havens.
Wonder of something similar is starting to happen to the other sites? Maybe some combination of legal and covert harassment? They're already pressuring the big search engines to not index any of the major filesharing sites, regardless of the legality of content the spiders identify.
