“The Recording Industry Association of America is suing 532 more individuals it says are illegally sharing copyright music over peer-to-peer networks, the group announced Wednesday. It’s the largest group of copyright-infringement lawsuits that the music trade group has filed since it began its crackdown on file traders in September. The latest batch of traders targeted by the RIAA are accused of distributing, on average, 858 music files. Currently the RIAA doesn’t know exactly who these people are, so it must use a ‘John Doe’ process to obtain the names of those it says are illegally sharing music. Defendants are identified by their IP addresses.”
