Nani Trap - Fraudster's worst nightmare

Nani Trap instead flips the call: It is a Gemini Live honeypot which answers as a real sounding elder, wastes the scammer’s time with natural barge-in conversations, and in parallel extracts a live dossier (scam genre, claimed institution, UPI/mule IDs, pressure tactics, transcripts) to report to authorities. Also protects elders from opening fishy links and giving tips. Full security Nani ji Who pays: adult children via a family plan - not the grandparents.
