# Fanfiction Communities Target AI-generated Fanworks and Detection Methods > Source: > Published: 2026-07-04 12:11:41+00:00 For AI and ML practitioners, the surge in community-built detection efforts highlights tensions between dataset provenance, model outputs, and social harm in creative spaces. The Verge reports that a new fanworks movement has emerged aiming to identify fanfiction written with generative AI, and that community-run detection methods are proliferating but producing questionable results (The Verge, Jul 4, 2026). Reporting shows these efforts can misclassify human authors and create social conflict within fandoms (The Verge). Earlier coverage documents that large language models are trained on scraped fanfiction, Gizmodo reported that **Archive of Our Own (AO3)** and other fan sites have been included in large web crawls used for model training, and Wired has covered related issues such as erotic chatbots and boundary concerns in fandom spaces.
