For years now, a porn studio called Malibu Media has filed more copyright lawsuits than any other company. Each month, Malibu, which produces adult content under the brand name X-Art, sues hundreds of “John Doe” Internet users, accusing particular IP addresses of illegally downloading their movies using BitTorrent networks.

Malibu’s owners, Brigham Field and Collette Pelissier Field, have said the flood of lawsuits is necessary to deter piracy. Now, though, they’re targeting the very lawyer who headed up their giant copyright enforcement campaign, Florida-based Keith Lipscomb.
