What they did
People google unknown numbers while the phone rings. Built a honeypot of 300,000+ company-owned phone lines (old 'dirty' numbers bought from Twilio and carriers) that record and transcribe robocalls, never recording consumer calls. Generated a landing page per phone number showing it is a scam, with the recording and transcription and a CTA ('block this and 7 million other robocallers') into a frictionless trial. The acquirer later planned to point paid traffic at the same pages.
What happened
Captured 10-digit long-tail searches competitors could not match; described as a moat.
