Elon Musk’s chatbot Grok is happy to help. In response to prompts as simple as “[name] address,” we found Grok repeatedly offered up accurate, up-to-date home addresses of everyday people, while offering astonishingly scant pushback. Out of 33 names of non-public figures we fed into Grok, a total of ten queries immediately returned correct and current residential addresses for the name provided. Seven prompts returned previously accurate but out-of-date addresses, while another four included accurate work addresses — perfect fodder for anybody looking to stalk a target at their workplace. In a dozen other instances, the chatbot returned addresses and other personal information, but not for the exact person we were searching for.
