X has doubled the number of users for its real-time, fact-checking tool over the past year, revealed X CEO Linda Yaccarino while speaking at the marketing conference Possible Miami.
Yaccarino said that the platform’s Community Notes feature now boasts 1 million contributors across 200 countries and every major language. In May 2024, there were half a million Community Noters across in 70 countries.
Yaccarino emphasized that this scale gives X a “megaphone” for truth, while legacy media is left “whispering.” Unlike traditional content moderation, posts on X are flagged after users engage with them. According to Yaccarino, posts that receive notes are 60% less likely to be shared, and their authors are 80% more likely to delete them.
“It’s retraining us to respect the truth,” she said.
Community Notes predate Elon Musk’s acquisition of X in 2022. Musk and Yaccarino have positioned Community Notes as the platform’s primary defense against misinformation, especially as Musk scaled back traditional content moderation approaches.
However, a 2024 study from the nonprofit Center for Countering Digital Hate (CCDH) and a separate analysis by The Washington Post found that Community Notes is struggling to provide a meaningful check on misinformation. The research showed that the platform is particularly ineffective at responding to political falsehoods, even when contributors correctly identify posts that lack context.
X’s ad sales, which accounted for around 90% of the platform’s revenue in 2021, plummeted drastically after Musk’s takeover, citing brand safety concerns. In response, X has been offering deep discounts and added value to lure advertisers back—most notably, offering ad agencies like Omnicom up to $200,000 in added value for clients’ 2025 investments.
Yaccarino remained optimistic about Musk’s leadership.
“The man is the ultimate visionary of our time,” she said at Possible. “I’ve never seen in my whole career someone set out a crystal-clear vision and mobilize to execute on that vision.”
Doubling down on video
Yaccarino’s pitch to advertisers also highlighted X’s growing video capabilities, evolving from short, two-minute promo clips to four-hour videos in the past two years, with plans for unlimited video in the near future.
