A user recounts using Grok to prove he was being followed during a custody dispute: it pointed him to the open-source Chasing Your Tail tool, deployed on a Raspberry Pi logging nearby phone signals. In 8 days one phone appeared 23 times across 9 locations (home, kids' school, office, gym), and its remembered Wi-Fi networks ("HartleyInvestigations", "JennaHome5G") identified a private investigator. Elon Musk amplified the story, praising Grok; the GitHub repo has 700 stars.
