The Recording Industry Association of America (RIAA) was much vilified for its suits a while back against random file-sharers who were distributing copyrighted music. Now it appears that the RIAA is proceeding against people who have copied legally-purchased CDs onto their own computers.
The question is, how did the RIAA find these people? Were they, in fact, engaging in file-sharing–or is there a code on the CDs in question which tipped the RIAA off? Something is not being fully reported here.
