Facebook Failed to Stop Ads Threatening Election Workers

The ads, submitted by researchers, were rejected by YouTube and TikTok.

Facebook says it does not allow content that threatens serious violence. But when researchers submitted ads threatening to “lynch,” “murder” and “execute” election workers around Election Day this year, the company’s largely automated moderation systems approved many of them.

1. Out of the 20 ads submitted by researchers containing violent content, 15 were approved by Facebook, according to a new test published by Global Witness, a watchdog group, and New York University’s Cybersecurity for Democracy. Researchers deleted the approved ads before they were published.
