Torrent sites under legal attack

Torrentfreak reports:

The MPAA [has] filed lawsuits against Torrentspy, Isohunt, Torrentbox, Niteshadow and Bthub. This could have a huge impact on the Bittorrent community since Torrentspy and Isohunt are two of the most frequently visited torrent sites.

But on the other hand, Isohunt and Torrentspy are torrent search engines and DO NOT host any torrents so the MPAA may have a hard time to built a strong case.
