I dunno if i agree with the consensus that nothing has been done here. It seems like an awful lot of piracy sites have been shut down recently- starting with TorrentSpy for U.S. users back in.. what was it... 2008? I feel like the RIAA and the other groups are on to something here. Shelling lawsuit after lawsuit at a website is a good way to get them to go bankrupt, unless the operator also happens to be a lawyer who can represent himself. Court battles are expensive, I'm surprised that ThePirateBay has stayed online through the numerous shutdown attempts its gone through.
I mean, that's not to say that people wont still find a way to get what they want, but the vast majority of the internet users who pirate content would be at a loss without their favorite torrent website helping them. I just get the feeling that in the next couple decades some form of regulation is going to be placed on these websites, in the U.S. at the very least.
