"BitTorrent Inc. discourages the use of its technology for distributing films without a license to do so," Cohen said in a statement. "As such, we are pleased to work with the film industry to remove unauthorized content from bittorrent.com's search engine."
It isn't all that widespread, apparently only referring to particular owned content, and relies on MPAA officials to find copyrighted material. This helps bridge the gap between illegal and illegal torrenting, however, which is a good thing. Torrents are a fantastic tool that has helped speed up the distribution of many things, such as large CD images. Some companies are even using torrents as a way to distribute files to their customers after purchase. It also helps that litigation has not been brought against Cohen, which has become almost industry standard these days.
