Ars Technica reports that the Department of Justice and the FBI seized the domain of Sharebeast.com on Friday in another victory in the ongoing war against illegal file-sharing. Sharebeast, which represented the largest U.S.-based file-sharing service — and was one of the top sites for pirated music and TV files in the UK — included related domains such as albumjams and mp3pet.com. “This is a huge win for the music community and legitimate music services,” said RIAA chair and CEO Cary Sherman. “Sharebeast operated with flagrant disregard for the rights of artists and labels while undermining the legal marketplace.”
