Copyright trolls: Malibu media, Prenda, time-travellers, the MAFIAA and how to defend yourself.

Porn studio Malibu Media’s habit of filing hundreds of cases then dropping them because their IP geolocation is so bad has annoyed the judge. William Alsup (pictured), long the bane of dodgy intellectual property litigants, has threatened to bar them from the Northern District of California unless they can show cause quick smart.
John Steele of Prenda Law has been disbarred by the Illinois Supreme Court, who were already investigating him before his recent guilty plea. And good riddance.
