While this seems satisfying, it would be more effective to figure out how these companies are still able to access the credit card networks and block the shit out of them. I used to work at one of the smaller international CC processors, and we specifically rejected merchants offering "remote technical support" (i.e., THIS EXACT SCAM) and the entire rest of the 5967 MCC (inbound teleservices).

I recall reading that the "fake IRS" crew had started working around this by telling people to buy iTunes gift cards, but it would be a start.
