In June, an anonymous account under the name John Doe and the handle @heatedrivalryjai on the social media platform X published a detailed report titled “Fandom Has a Hidden Generative A.I. Problem,” which identified 38 popular fan fiction stories based on the male-male hockey romance series “Heated Rivalry” as containing text generated by the artificial intelligence chatbot Claude, developed by Anthropic. The document triggered widespread discussion and controversy within the fan community, drawing attention to the use of generative AI in creative writing without disclosure.
“Heated Rivalry,” originally a series of novels by Rachel Reid that debuted in 2018, gained renewed popularity following its television adaptation on HBO Max, starring Hudson Williams and Connor Storrie. The fandom rapidly expanded, with fan-created stories flooding platforms such as Archive of Our Own (AO3). By November, more than 223 fan fictions were available, and the total stories surged to over 43,000 after the show’s premiere. Many fans expressed alarm as some fan fiction works exhibited rapid output and stylistic patterns consistent with AI generation, leading to growing concerns about authenticity and the role of human creativity in these spaces.
The report by John Doe identified AI-generated content by detecting distinctive HTML coding tags left behind by texts produced by Claude. The document's release prompted intense reactions including accusations and online harassment of authors named in the findings, with some writers deleting or locking their accounts and adding disclaimers about AI use. Among those affected was a popular fan fiction author using the handle OpalApparition, whose widely read story “Nutcracker!” was found to contain traces of AI-generated text despite the author’s prior public opposition to such tools.
The incident has exposed a rift within the “Heated Rivalry” fan base. Some community members supported the report, viewing it as a necessary intervention to preserve the integrity of fan creativity. Others described the backlash as a “witch hunt,” criticizing the fervor and the public naming of authors, asserting that the matter was complex and that some accusations lacked definitive proof. Comments from fans reflected feelings of betrayal and a sense that the community space had been violated by undisclosed AI use.
Attempts to obtain comments from key figures associated with “Heated Rivalry,” including author Rachel Reid, series creator Jacob Tierney, the actors Hudson Williams and Connor Storrie, and HBO Max, were unsuccessful. Meanwhile, the individual or group behind the John Doe account, communicating under the pseudonym Ghostiesdagger, stated their mission as protecting human creativity within fandom and building community, despite anonymity.
The controversy highlights ongoing tensions in creative fan communities as artificial intelligence tools become more accessible. It raises questions about transparency, the limits on AI-generated content, and the preservation of spaces dedicated to human-driven storytelling. While some see disclosure and moderation as necessary, others warn against hasty judgments and emphasize the need for nuanced conversations on the future of fan fiction and AI integration.
