Game of Thrones pulled in almost 8 million viewers for its premiere on Sunday (a new record for the HBO series), but how many people were watching live over Periscope? Probably not very many, but that didn’t stop HBO from sending take down notices to the Twitter-owned live streaming app.

“We are aware of Periscope and have sent takedown notices,” HBO said in a statement to The Hollywood Reporter. “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.”

For now, Twitter and Periscope rely on external reports of copyright infringement, meaning your Game of Thrones live stream won’t be cut short unless HBO catches it (or your signal drops). However, videos shared on the streaming app only exist for 24 hours, so many will have already disappeared before the company can react.

Speaking to Australian site Mumbrella, Twitter warned that continuos offenders could face pretty harsh repercussions. The company pointed to its terms of service, which warn that “Periscope will also terminate a user’s account if the user is determined to be a repeat infringer.”

HBO’s bigger problem may be illegal downloads, not live streaming apps like Periscope. Game of Thrones is one of the most popular shows on many torrenting sites. The first four episodes of season 5 even leaked online ahead of the premiere, where they were quickly downloaded over 100,000 times.

Still, it’s probably not worth Periscoping next week’s Game of Thrones if you don’t want Twitter to delete your account.
