I asked my friend to check his memories, and to probe Chat GPT about when it had gained knowledge of my pet's name, it felt like it "hallucinated" the answer as it doesn't have memory entries about my pet's name on my friend's account, it said something like my friend had told him about it last year (which he did not), and we do not share an account. Each of us have our own accounts.

The one thing I could think off was that my wife was on the free account for a while last year, and she likely used it to ask all sorts of things related to our pets, and I believe free accounts are fair game for training data. Still, for a generic prompt to one-shot my pet's name to a close connection was very strange to me.

Maybe the fingerprint (wifi profile, iOS device, etc) caused the training data to be more biased?

This sure got me thinking of how this can/could be exploited further though.
