MIT Technology Review finds ChatGPT revealed phone number and address
MIT Technology Review found that ChatGPT gave out a real phone number and address from old public records when asked: a reminder that chatbots can sometimes surface sensitive information that is already available in public records.

ChatGPT, though, shared both correct and incorrect information without hesitation.
