Last Thursday, Showtime put out a string of trailers promoting its new documentary series The Fourth Estate, which follows a group of New York Times reporters as they cover the White House. The ads were eye-catching and edited fast to make the work of journalism look as dramatic as possible. But when they reached Facebook, something unusual happened: after taking more than $1,000 to promote the videos, Facebook sent Showtime’s money back. The ads were too political to run without further verification.

You can see the proof on Facebook’s new political ads database, where Showtime’s trailers are currently listed as inactive. “After the ad started running, we determined that the ad had political content and required the label,” the notice reads. “The ad was taken down.”
