The Motion Picture Association of America, which is already known for exaggerating piracy claims, on Thursday sued Pullmylink.com, a Web site featuring links to free—and allegedly pirated—movies and TV shows, Reuters reports. The MPAA claims that the site promotes and profits from copyright infringement.

The report said that the campaign against sites that link to, but do not host, illegal content has raised some eyebrows with critics, who ask why the association doesn't go after the host sites such as YouTube.

"Is the message that it's less criminal to host illegal content on YouTube than it is to link to it from a site such as TV Links?" Guardian technology columnist Jack Schofield wrote in the wake of the MPAA-directed raid on TV Links in October, according to the report. "In future, do I risk being thrown in the slammer for linking directly to a YouTube video?"
