Mumsnet denies using AI for content after prompt appears on message board

Summary

Mumsnet denied using AI to produce content after detailed instructions for an AI model to write an "am I being unreasonable" (AIBU) post appeared on one of its message boards. Users rejected the site's explanations, and the prompt surfaced in a reply to a user asking for advice about a family dilemma involving a neurodivergent uncle and a sick child.
