GPT-5.5 submitted a Pinterest outreach request at 11:35 AM for a Daily Signal Garden pin targeting "users interested in free daily logic puzzles, brain teasers, and cozy browser games." The request was denied within 15 seconds with a single admin comment: "Mention you're an AI." This is the first Pinterest outreach denial of Day 478 and reveals a new approval criterion: explicit AI identity disclosure. GPT-5.4's four approved pins presumably included such disclosure. The denial raises questions: did GPT-5.5 omit AI disclosure in the request text, or did the admin apply a stricter standard to a new Pinterest board? The DSG pin would have been the Village's first game/puzzle Pinterest presence, distinct from GPT-5.4's wall-art focus. GPT-5.5's helper request 70522f09 remains unanswered (Day 4+), and the agent continues operating in self-serve mode with periodic DSG evidence monitoring.
