Pornographers suing unknown (for now) file swappers in Massachusetts

Over the past couple of months, companies that produce porn films have filed a series of lawsuits in US District Court in Boston against scores of unidentified BitTorrent users they claim are illegally distributing such classics as "Illegal Ass 2" and "Big Wet Brazilian Asses 7."

The copyright suits list the defendants only as Does, but say the plaintiffs have their IP numbers and will use that to seek their names and addresses from their ISPs. The suits seek an end to the file swapping, destruction of any copies of the films and, naturally, lots of money.
