A fellow has done a good amount of work in downloading links from The Pirate Bay as well as information from the site. He's released it all and posted some analysis of it here:http://runn1ng.github.com/piratebay.html
Lots of graphs and stuff.
Pirate Bay archival
Some time ago, I did an experiment on how small I can make all pirate bay while keeping the important information. People apparently liked it.
Well, now some months later, I wanted to do two things - first, make it even smaller and correct all the mistakes I did before. Second - I wanted to create another version that will have all the additional information - most importantly, all the comments and text information. For me, pirate bay is not just the torrents, but mainly the additional information - how fake is the file? What can I really expect inside?
So I did both.
You could reconstruct TPB from that information. (mostly)
