The two organizations hadn't actually been keeping a register of offenses beforehand anyway, they were simply sending the information onto the relevant ISPs.

First guess they will be all over piratebay.org sense it is run in sweeden. GET PEERGUARDIAN!
They cant do anything to thepiratebay.org ,all they do is host trackers, no actual material. The material is of course transferred via bittorrent , so its split up into many small incomplete pieces. How can they keep track of incomplete data from various sources, well enough to even get a warrant based off of a IP address. Peerguardian isnt going to stop anyone from logging your ip address and trying to sue you,itll just keep them from connecting to your computer
I think a few sites have been taken down for only hosting trackers so I don't know.
1. Blocklist Manager 2. ProtoWall 3. MUTE This is just spurring the development of anonymous file sharing.
