4 Dominant Themes in the Discussion

# Theme Supporting Quote
1 Shared “family password” / code word as a cheap, reliable safeguard The best things to stop these AI voice schemes, is to agree on a family password.” — root‑parent
2 Defensive call habits – silence, brief “hello”, or refusing to engage I mostly answer unknown calls with monotone “hello” and then wait for their introduction before talking normally.” — ActionHank
I answer with silence. I wait for them to speak first. Not even once has a scammer ever spoken first.” — fhdkweig
3 AI‑generated voices make scams scalable and erode trust INTERPOL found that AI‑enhanced fraud is roughly four and a half times more profitable than its traditional equivalent.” — forgets79
4 Systemic / regulatory fixes – curb money‑transfer pathways and enforce identity proofing What all these scams rely on is a way to transfer money in an irrevocable fashion. Restrict that in meaningful ways and you end a lot of the abilities for these scams to operate.” — cogman10
