Operators of “The world’s most resilient bittorrent site” The Pirate Bay gets their appeal underway after a year they were found guilty of breaching copyright laws. The Pirate Bay, a Swedish website that indexes BitTorrent (.torrent) files, has been involved in a number of lawsuits, both as the plaintiff and as the defendant. Launched in 2003, the website helps web surfers share copyrighted music and film files, which is illegal in many countries, including Sweden.
