Fifa’s Social Media Protection Service says harmful posts and comments during the 2026 World Cup were 14 times higher than in 2022.
More than seven million messages were identified and removed this summer.
That compares with 470,000 such posts and comments at the previous tournament.
Fifa also recorded over 200,000 abusive or threatening posts and comments, up from 19,600 at Qatar 2022.
More than 15,000 posts were escalated for further action, and over 1,000 egregious threats were referred to relevant authorities, including law enforcement.
The Social Media Protection Service (SMPS) is a digital safeguard available to all teams, coaches, players, and officials in Fifa tournaments.
During the 2026 World Cup, co-hosted by the United States, Canada, and Mexico, it moderated more than 53 million posts and comments.
AI flagged over 530,000 messages targeting specific individuals, which the SMPS team assessed.
