Well here they already removed piratebay from the dns of one of the biggest isp's. No other sites were affected. Even youtube with it's copyrighted
material stays online just nice. So you dont need a SOPA to get rid of sites.
Over on Techdirt, Mike Masnick has pointed out the mother of all ironies: The Pirate Bay, one of the largest outlets of copyright infringement, would be immune to the takedown tendrils of the imminently incoming Stop Online Piracy Act (SOPA).
Apparently it all comes down to the fact that The Pirate Bay has a .org domain — and according to Masnick, the current version of the SOPA bill working its way through congress excludes American domestic domains from being the target of takedown notices from copyright holders. In this case, a “domestic domain” is any domain that comes from a TLD run by an American registry — and sure enough, .org’s registry is Public Interest Registry, a US non-profit based in Virginia. In other words, thepiratebay.org isn’t eligible for a SOPA-based takedown, even if its servers are based in Sweden or another country outside the US.
