The makers of Game of Thrones are taking action against Pornhub over breach of copyright.

HBO says it's because some scenes from the show have appeared on the site.

Some other videos even include parodies of porn stars pretending to be characters such as Cersei Lannister and Lord Varys from Game of Thrones.

In a statement, HBO said: "HBO is aware of the issue and is in the process of getting material taken down from Pornhub."

Pornhub's vice president, Corey Price, told Newsbeat that it takes illegal material down as soon as it becomes aware of it.

"Pornhub is fully compliant with the law," he said.

"We respect all copyright requests and once received immediately remove any infringing content, as well as offer content fingerprinting to block infringing content from being uploaded by content owners."

Last month, Pornhub released data saying that in April, searches containing Game of Thrones were slightly above average but they shot up in the days before the series premiere.

The site said that traffic peaked at 370% on Sunday 24 April in America.

"More specific searches include Walk of Shame, referring to a scene in which the character Cersei was forced to walk naked through the town," it added.

The site said that other television series searched before Game of Thrones include The Walking Dead and True Blood.

Game of Thrones has made headlines on a number of occasions due to its graphic content, which includes incest, rape and full frontal nudity.

Emilia Clarke, who plays Daenerys Targaryen (the Queen of Dragons), was the top search.

She was closely followed by Natalie Dormer as Margaery Tyrell and Sibel Kekilli, who played Shae.

Jon Snow has also been searched for on the site.

We asked Pornhub for a statement but haven't heard anything back yet.
