The Recording Inddustry Association of Amercia (RIAA) has begun litigation against 500 plus persons. One slight problem...
They don't know who they are.. Yet...

Since the courts ruled in December that the RIAA cannot force any ISP to release the names and address of their clients under suspition of priating music, RIAA has to submit individual subpoena's for each suspect forcing the ISP's to spill all.

This has become a great task for the RIAA, and they seem to be not letting down.
