iTunes Purchases Help U.S. Authorities Find 'KickassTorrents' Leader

Artem Vaulin is accused of being the mastermind behind the most popular illegal file-sharing site in the world, KickassTorrents, which U.S. authorities say helped distribute more than a billion dollars' worth of pirated movies and music. Yet despite allegedly making a living from helping people steal copyrighted material, the 30-year-old Ukrainian seems to have bought movies and music legally on iTunes — and some of those purchases ultimately helped investigators track him down, according to a criminal complaint lodged against him in federal court.
