How to handle political ads on social media has become a growing concern as the 2020 U.S. presidential election approaches.
Facebook has taken most of the heat, after refusing to remove an ad for President Trump's reelection featuring false information about his opponent Joe Biden.
While political ads on social media do not adhere to different rules than political ads on TV, they have come under specific scrutiny because of their unique ability to disseminate – broadly and rapidly -- bad information, and the platforms' inability to properly police them.
Compared to TV, online ads can spread lies at an alarming rate -- bolstered by machine-learning algorithms that can identify target audiences at enormous speed and scale.
In October, responding to a groundswell of concern, Twitter announced it would ban political advertising on its platform. Google and its subsidiary YouTube do not ban these ads, but the company last month came out with adjustments and clarifications to its policy, including limiting microtargeting of users.
