On Tuesday, the Motion Picture Association of America filed yet another suit against the Swedish-based file sharing site on behalf of 13 studios including Columbia Pictures, Disney Enterprises and Universal Studios. The MPAA is seeking to shutter the site, claiming copyright infringement.

"I'm on vacation, sleeping a lot and eating great vegan food," Sunde told the BBC. "The latest threats are just harassments from the industry of course. We've actually asked the courts to punish them with a high fine for the faulty threats."

In April, the MPAA won its infringement lawsuit in Swedish court against Sunde and three other Pirate Bay co-founders, Gottfrid Svartholm Warg, Fredrik Neij and Carl Lundstrom, who were sentenced to a one-year prison sentence and a fine of 30 million kronor (roughly $4 million). Despite the ruling, the court never ordered Pirate Bay to shut down, the BBC said.

"We have filed a complaint against Pirate Bay because they have not stopped their activities after they were sentenced to prison," Stockholm lawyer Monique Wadsted, who is representing the MPAA, told news agency AFP.

Pirate Bay immediately filed an appeal against the ruling, but lost, and has filed a second appeal that is still pending.

Meanwhile, Swedish software company Global Gaming Factory X is slated to acquire Pirate Bay in a cash and stock deal worth roughly $7.7 million in cash and stock. The acquisition is expected to close in August.

Global Gaming said it will change Pirate Bay to a legal download Web site and pay copyright fees.

"In order to live on, Pirate Bay requires a new business model, which satisfies the requirements and needs of all parties, content providers, broadband operators, end users," said Hans Pandeya, Global Gaming's chief executive, in a statement.
