A video posted on Instagram shows Facebook's CEO Mark Zuckerberg saying: "Imagine this for a second: One man, with total control of billions of people's stolen data, all their secrets, their lives, their futures," Zuckerberg's says in the video. "I owe it all to Spectre. Spectre showed me that whoever controls the data, controls the future."

There's one small thing about the video: it's fake.

Another thing: Facebook's (and thus Instagram's) policy is to not remove this type of video. But what about when it's about its own founder and CEO?

As of Tuesday afternoon, the video was still live on Instagram.

According to Vice News, two artists, Bill Posters and Daniel Howe in partnership with advertising company Canny, posted the fake video of Zuckerberg on the social network. The video shows Facebook's founder and CEO, Mark Zuckerberg, sitting at his desk, as if he were talking on CBS with a news caption at the bottom saying "we're increasing our transparency on ads".

What Instagram is going to do about this video raises questions now, as the social media company decided to keep similar videos live in the past.

When an altered video of House speaker Nancy Pelosi started spread on social media and it quickly became clear this video had been manipulated to make her sound as drunk. Facebook decided to de-prioritise it instead of deleting it.

“We think it’s important for people to make their own informed choice for what to believe. Our job is to make sure we are getting them accurate information,” a Facebook official told Anderson Cooper last May.

At the time, when asked whether a similar video of Zuckerberg would stay online if posted, the answer of Facebook was yes. However, the Facebook official was talking about a slowed down video, not a fake one.

Bill Posters posted deepfake video of Donald Trump on his account in the past - both of which are still online.
