"Game of Thrones" star Maisie Williams Arya Stark was a victim of cyberbullying as Arya Stark talked about her own experience with Internet trolls.

In the behind-the-scenes video to promote "Cyberbully," Maisie Williams confessed to be a victim of cyberbullying even up to now when her career blew up for her turn as Arya Stark in the massively successful HBO series, "Game of Thrones."

"I encounter trolls on the internet firsthand all the time," she said. "As soon as someone finds out something you're insecure about or that bothers you, they will use that against you, which is awful."

She said it's easy to dismiss the cyberbullying and online attacks, but they do affect her.

"It's easy to say, 'It's just a troll - they don't know you,' but it does hurt,'" "Game of Thrones" star Maisie Williams added.

The description for made-for-TV feature "Cyberbully" reads: "A chilling real-time thriller starring Maisie Williams - from Game of Thrones - as a teenager battling with an anonymous cyber-stalker. The plot of Cyberbully is inspired by dozens of real-life cases.

As "Game of Thrones" star Maisie Williams explained: "Casey is a very normal teenager who expresses herself through alias names on the Internet. There she can post what she finds happy and what she finds sad, until someone takes over her computer and makes her out to be some she isn't."

"Everyone can be portrayed as something different if someone has access to all of their files," she said.

"Game of Thrones" star Maisie Williams also said that in making "Cyberbully," what they want the viewers to take away "was an honest representation of teens on the Internet - without being patronizing or using embarrassing text speak. As soon as you put in too many LOLs teenagers switch off because they don't think it's honest."
