Facebook tells advertisers more scrutiny is coming

Facebook is going to require advertisements that are targeted to people based on "politics, religion, ethnicity or social issues" to be manually reviewed before they go live, according to an e-mail sent to advertisers. That's a higher standard than that required of most Facebook ads, which are bought and uploaded to the site through an automated system. It's also warning that it expects the new policy to slow down the launch of new ad campaigns.

The steps Facebook is taking to combat questions of Russian election interference strike at the core of the company's business. The ad buyers who spent $450 million on Facebook ads love the platform's speed and efficiency — something they fear will be diminished by inserting more human oversight of political ads before they go live. The company's action comes as a political ad disclosure bill gains momentum on Capitol Hill.
