  type: PropertyValue
  value: Relies on visceral user testimony and emotionally charged language ('unfamiliar data', 'presented as information about me') to create urgency and legitimacy — but offers zero technical anchors (version, config, logs) to ground the claim, making independent assessment impossible and shifting burden of dismissal onto skeptics.

  position: 1
  item: Claim
    text: ChatGPT sent me a string of very detailed data (completely unrelated to my first message) that I do not recognize, never provided, and that was presented as information about me. It looked like it was data obtained from another account/chat history and shown to me by accident.
    appearance: I wanted to rant to chatgpt a bit today. After I sent my first message, it sent me a string of very detailed data (completely unrelated to my first message) that I do not recognize, never provided, and that was presented as information about me. It looked like it was data obtained from another account/chat history and shown to me by accident.
