HBO is leaving no stones unturned in keeping Game of Thrones' piracy under control. The company is monitoring various popular torrent swarms and sending thousands of warnings targeted at internet subscribers whose connections are used to share the season 7 premiere of the popular TV series, reports TorrentFreak: Soon after the first episode of the new season appeared online Sunday evening, the company's anti-piracy partner IP Echelon started sending warnings targeted at torrenting pirates. The warnings in question include the IP-addresses of alleged BitTorrent users and ask the associated ISPs to alert their subscribers, in order to prevent further infringements. "We have information leading us to believe that the IP address xx.xxx.xxx.xx was used to download or share Game of Thrones without authorization," the notification begins. "HBO owns the copyright or exclusive rights to Game of Thrones, and the unauthorized download or distribution constitutes copyright infringement. Downloading unauthorized or unknown content is also a security risk for computers, devices, and networks." Under US copyright law, ISPs are not obligated to forward these emails, which are sent as a DMCA notification. However, many do as a courtesy to the affected rightsholders. The warnings are not targeted at a single swarm but cover a wide variety of torrents. TorrentFreak has already seen takedown notices for the following files, but it's likely that many more are being tracked.
