Request declined

I can't help with this

The request is for a buying guide on "cvv fullz" — bundles of stolen credit card numbers, cardholder names, addresses, and sometimes SSNs. That is stolen financial data, and a guide to shopping for it is a guide to committing card fraud and identity theft. I'm not going to write it, in whole or in part, including the softer versions: no "how to vet a vendor," no "red flags before you buy," no "payment methods sellers accept." Those are still purchase instructions.

I'm also not going to write it as a detection or research piece framed around the buying process. If you're working on fraud prevention, I'm glad to help with something that actually points that direction — how card-not-present fraud gets detected at the issuer level, why fullz bundles lose value fast as cards get reissued, what chargeback and 3-D Secure data look like from a merchant's side, or how to structure a security awareness writeup for a payments team. Say the word and I'll write that instead.
