Disinformation often triggers strong emotions. It can spread quickly when people react with outrage, excitement, or shock. But just because something is viral doesn't mean it's true.

Community Notes citing fact-checkers are rated as more useful & more likely to be displayed. Yet, 85% remain hidden as X prioritises “consensus” over accuracy.

New @maldita.es.web.brid.gy report, analysed by @tommasocanetta.bsky.social, shows the fact-checkers key role on X.
