HBO is having a major 'Game of Thrones' problem with Periscope.
The live streaming app is being used as a crude method of watching the new series illegally and while Twitter has said it's cracking down, HBO is taking things a step further.
The company has started sending 'take down' notices to Twitter as a response to the sheer number of people who chose to use Periscope as a way of illegally streaming the premiere of season five.
In a statement to the BBC that indirectly targets the social media company HBO said:
"In general, we feel developers should have tools which proactively prevent mass copyright infringement from occurring on their apps and not be solely reliant upon notifications,"
Twitter has responded to the problem saying that it's actively targeting those who repeatedly break the term and conditions while reiterating that Periscope operates well within the confines of US copyright law.
HBO has historically found 'Game of Thrones' to be a pirating nightmare with the show regularly appearing as one of the most illegally watched TV shows in the world.
The company suffered another significant setback last weekend when the first four episodes of the series were leaked online by a group that had reportedly been sent the episodes to review.
