The Motion Picture Association of America (MPAA) has been legally pursuing Web sites associated with movie piracy, including several sites that serve as search engines for the last three years. MPAA had described TorrentSpy.com as "an one-stop shop for copyright infringement" in the past.
But TorrentSpy's decision to shut down their popular web site came after a federal judge in Los Angeles ruled against TorrentSpy.com in favor of all six of the MPAA member companies last December.
The December's decision forced TorrentSpy to apply a filter against copyright files. When that didn't work it began blocking American IP addresses. But these restrictions resulted in a slide in the popularity of TorrentSpy among file sharers, giving its crown as the most popular BitTorrent tracker to the Pirate Bay.
BitTorrent sites are currently under pressure, facing the reactions of record, software, and film industries. Japanese companies plan to cut off the Internet connection of anyone who illegally downloads files in one of the world's toughest measures against online piracy.
France late last year also outlined similar measures to disconnect Internet users who flagrantly violated copyright laws.
In addition, Swedish courts will soon be able to force local Internet providers to produce information on suspected file-sharers in a move to crackdown on piracy. File-sharing can be traced by tracking the IP addresses of the computers that download or distribute a file.
