When a Fan Detector Turned AO3 Red: What Happened in the Heated Rivalry Fandom

Fans of the show Heated Rivalry feel upset and confused. An anonymous X account called @heatedrivalryai posted a document on June 29, 2026 that showed hidden code in some stories on Archive of Our Own (AO3). The document showed that the code came from the AI called Claude when text was pasted directly into AO3. Many readers found this surprising and some felt betrayed.

The document listed 38 works and offered a browser skin that highlights those stories by turning the page red. People argued online and some authors put their works on private or turned off comments. AO3 still accepts all fanworks, including AI-assisted ones, but the community debate is loud.
