Meta's AI moderation fails to flag election misinformation on Facebook
Meta's moderation systems failed to flag recurring election misinformation on Facebook ahead of the 2024 U.S. presidential election, even though the same false voting instructions had been flagged during the 2020 election. Election officials in multiple states reported that the misinformation spread widely without any Meta intervention until state and local authorities issued their own warnings.
What happened
A Facebook post containing false voting instructions circulated widely in July 2024, advising voters to request new ballots if poll workers wrote anything on their ballot forms because it would be invalidated. The same misinformation had spread on Facebook during the 2020 election, when Meta flagged it as false information with a link to a USA Today fact-check.
In 2024, the same post spread without any Meta moderation label or fact-check link. The misinformation was widespread enough that the North Carolina State Board of Elections issued a press release on August 2 warning that such posts had been circulating for years and had resurfaced in multiple counties. Multiple Facebook users in North Carolina, Mississippi and New Jersey continued sharing the ballot misinformation without any notification that it was false.
Reported impact
Derek Bowens, director of elections in Durham County, North Carolina, said he faced a potential crisis when the misinformation began spreading virally. Election officials across the U.S. expressed concern about Meta's ability to control misinformation as the 2024 presidential election approached, citing the spread of false claims that threatened to disrupt voting.
Index analysis
Meta had reduced its trust and safety and customer service staffing through layoffs and deprioritized news content, making it difficult for election officials to dispel misinformation. When CNBC flagged posts with the false information to Meta, a company spokesperson said the posts had been sent to third-party fact-checkers for review, but no moderation action was taken before state and local officials intervened.
