ArsTechnica: “We Just Link To Videos! won’t stave off MPAA Lawyers”:

But the key question is whether sites like Campusist are engaged in that piracy, or whether the fact that they simply link to other sites grants them immunity. This latter argument is the one routinely advanced by The Pirate Bay and other torrent trackers. But, when every link on a site leads to an infringing copy of a film, does the “Hey, I’m just linking to some stuff!” argument still carry weight?
The MPAA doesn’t think so, and yesterday it filed suits against three websites: Campusist, Movies-on-demand.tv, and Sswarez.com. The move is part of MPAA’s continuing legal campaign to target distribution sites, and the film business has yet to engage in the sort of widespread suing of individuals that has characterized the music industry’s approach.
