A handful of anonymous bots have taken over fact-checking on X.

This isn’t hyperbole. In the first three weeks of May, just eight AI contributors wrote 50.3% of all visible Community Notes on the platform.

When the program launched five years ago, X positioned it as a way to harness the knowledge of users to add context and corrections to tweets. It described Community Notes as a way to “broaden the range of voices” fighting misinformation.

Then, in July 2025, X started allowing people to use automation to mass-generate and submit AI notes. That new feature made it inevitable that human writers would eventually be overtaken by bots. But it happened faster than I predicted.
