Millions download HBO’s high-fantasy drama “Game of Thrones” episodes illegally via torrent sites. It was the most pirated show of 2015. However, in a case very similar to Daenerys Targaryen’s abolition of slavery in the show, HBO is raging a war on torrent sites, spoiler video channels and torrent users to end GoT piracy.

Torrent Freak reported that the channel is not only taking stern actions against those who download the show illegally via torrent sites, but also reviewing spoiler sites and video channels that predict what is going to happen in future episodes.

“Game of Thrones” fans who have not subscribed to HBO either visit a friend’s place to watch the episodes or simply download them illegally via torrent sites. The show has set a piracy record as it was the most pirated show of 2015. Millions download as they refuse to pay HBO's high fees. The fact is HBO is not waiting for “Winter” to arrive and has already started taking action.

“As the owner of the IP address, HBO requests that [ISP] immediately contact the subscriber who was assigned the IP address at the date and time below with the details of this notice, and take the proper steps to prevent further downloading or sharing of unauthorised content and additional infringement notices,” read the letter HBO emailed Internet Service Providers (ISP).

The letter urges ISPs to track and contact subscribers who download “Game of Thrones” episodes through torrent sites. YouTube user Frikidoctor, who posts online videos of predictions in Spanish, has already faced the HBO blow. Frikidoctor claims to have sources that leaks information to him. In recent weeks, thousands of pirates received warning messages from HBO. Numerous torrent links were taken down.

Therefore, if one is thinking of downloading a "Game of Thrones" episode via torrent, HBO is watching.
