Torrent Spy was a great site indexing torrents that people had uploaded. Sadly it shut down world wide due to legal reasons.

This is a quote from Wikipedia:

TorrentSpy was a popular BitTorrent indexing Web Site. It tracked torrent files (which were hosted externally) and provided a forum to comment on them. It also integrated Digg-like user-driven content site ShoutWire's feed into its front page. In August 2007 there were more than 1,000,000 torrents indexed with thousands of new torrents indexed every day.[1] The Motion Picture Association of America filed a lawsuit in February 2006 for TorrentSpy facilitating copyright infringement as many torrents on its site were copyrighted films. In December of 2007 the court ruled against TorrentSpy for "widespread and systematic efforts to destroy evidence and have provided false testimony under oath in an effort to hide evidence of such destruction."[2] On March 24, 2008 facing further fines for not cooperating with the court TorrentSpy shut itself down.[3] On May 7, 2008, a federal judge ordered TorrentSpy to pay the Motion Picture Association of America $110 million for infringement of thousands of copyrighted film and TV shows. In a four-page final ruling, U.S. District Court Judge Florence-Marie Cooper entered the multimillion-dollar judgment against TorrentSpy parent company Valence Media for willfully inducing, contributing and vicariously allowing copyright infringement on its Web site. Cooper also issued a permanent injunction against the Web site, which shut down March 24. The MPAA, which represents the Hollywood studios, filed suit against TorrentSpy in February 2006, claiming that the site's torrent files were illegally uploaded. "This substantial money judgment sends a strong message about the illegality of these sites," MPAA chairman and CEO Dan Glickman said. "The demise of TorrentSpy is a clear victory for the studios." Whether the MPAA will collect the $110 million from TorrentSpy remains to be seen. Court records show that Valence and TorrentSpy principals Justin Bunnell and Wes Parker have filed for bankruptcy.[4]
