This article is from a few years ago, so the scammers’ methods may have changed since then. Seems like these low-rent Florida boiler room operations are serving as “lead generators” for slightly more “legitimate” independent resellers for Yext. Yext itself, like 99% of internet businesses, is arguably a scam, a rent-seeking wannabe middleman of dubious utility to anyone.
The scam is difficult to bait beyond short-duration calls because the scammer will hang up if they don’t get 1. A business, 2. A Google Business Profile for said business, and 3. A credit card number, all within a few minutes of their answering the phone. Furthermore, one or more of the groups running the scam have stopped taking call-backs entirely. They will only connect to a live scammer/operator when the recipient of the robocall presses a key during the robocall itself. If you call the number back, all you get is an IVR that says “press 1 (or some number) to opt out.”
