Gamefront reports that several large, international publishers have been sending out letters to alleged European pirates, ordering them to pay sums of up to 800 Euro (approximately $1000) for every illegally obtained copy of their video games. Publishers that have been sending out these letters supposedly include Codemasters, Square Enix, Atari, and Ubisoft. According to additional information provided by TorrentFreak, these publishers are tracking down users based on IP addresses. No official statement regarding these letters has been made by the publishers.
Polish developer / publisher CD Projekt recently launched a similar attack on European pirates of The Witcher II, though it called these plans off after the company began facing strong opposition from the PC-gaming community.
