In an effort to gain more subscribers HBO launched its standalone “HBO Now” service earlier this year.
The subscription allows Americans to access HBO’s content, including Game of Thrones, without the need to have a television subscription.
With the offer HBO hopes to drive people away from pirate sites, but it also created a new form of unauthorized use. As with Netflix and Hulu, many people outside the U.S. signed up for the service through VPNs and other geo-unblocking tools.
While Netflix is still fairly lax about geo-unblocking, HBO is now cracking down on the practice. A few days ago thousands of VPN and proxy “pirates” started to receive worrying email warnings.
