It’s a common tactic for pornography producers trying to protect their product from online piracy: They sue unknown “John Does” who illegally download movies, then go to internet providers to learn their true identities and collect.

Hundreds of porn companies have filed thousands of lawsuits across the country in recent years. Often, representatives will call up the defendants, offering quick settlements of $1,000 or $5,000 to avoid facing $150,000 claims and the embarrassment of being publicly outed.
