A spokesman didn't confirm or deny the claims, but did reiterate to the WSJ that Facebook was "looking at different ways [it] might refine" its stance on political ads.

If the approach sounds familiar, it should. Google recently limited political ad targeting to age, gender and general location, making it difficult to manipulate specific audiences. Twitter also restricted issue ads by excluding important criteria and banning certain keywords. Facebook would really be following suit, although the approach as described would allow more narrowly targeted ads than others.

There's certainly pressure to take action. The 2020 US presidential election is less than a year away, and there are concerns that hostile governments and unscrupulous politicians might use highly targeted ads to push fake claims and sway votes in important regions. A Facebook ban wouldn't completely halt this practice, but it might discourage the kind of behavior seen in 2016.
