Facebook is worried about losing the public’s trust, and so it’s making a move to bring more human control over ads on its platform.

Facebook is making changes to its advertising policies following the confirmation by a federal investigation that the company unknowingly sold more than $100,000 worth of ads to Russia which was allegedly trying to sway the 2016 U.S. presidential election. And according to Recode, Facebook intends to hire 1,000 additional people to add them to its internal team that reviews on its platform and removes them if they contravene its policies.

Facebook is also preparing to invest even more in machine learning, to “better understand when to flag and take down ads,” but it’s the first time the company will bring in more “human capital” to its ad reviewing team – especially at such a scale.

Concerning its ad product itself, Facebook announced it will now also “require more thorough documentation” from advertisers looking to promote political views on Facebook. The company is also working on a feature that will let users see a list of all the ads that a Facebook Page is running, even if the user himself is not part of their selected audience.

With more transparency, more control over advertisers, and a very large team of people looking over ads, Facebook is hoping it will regain the trust its business requires.
