I followed the link to find out that those researchers from INRIA claimed their attacks also worked for BitTorrent users on Tor. I didn't believe it at first but then today, I found this link on the Tor Project: http://blog.torproject.org/blog/bittorrent-over-tor-isnt-good-idea. It seems their attacks don't only link your real IP to your BitTorrent files on Tor but also to the webpages that you're browsing! Tell me it's a joke.
