Paul Hansmeier, one of the masterminds behind the “porn trolling” scheme known as Prenda Law, has had his license to practice law suspended indefinitely. He can’t ask for his license to be reinstated for at least four years.

Hansmeier and his colleague John Steele acquired copyrights to porn films and then sued thousands of “John Doe” defendants for allegedly illegal downloads of those films. Prenda Law made several million dollars before unraveling under a barrage of judicial sanctions beginning in 2013.
