A Facebook executive says the social network will begin using paper postcards to try and stop foreign meddlers—for instance, Russian agents—from buying ads designed to influence U.S. elections. Before the 2016 Presidential election, nearly 10 million Americans saw ads that were linked to Russia’s elaborate propaganda campaign.
To try and prevent that from happening again, Facebook says it will mail ad buyers a postcard bearing a code. According to Katie Harbath, Facebook’s global director of policy programs, “You will have to use that code to prove you are in the United States.” Harbath’s comments came at a weekend conference of state government officials and were earlier reported by Reuters.
