Why I'm turning this down
The keyword here isn't ambiguous. "Sell CVV dumps" describes the trade in stolen payment card records, and a buying guide would be instructions for committing card fraud. That's not a content question I can answer with better sourcing or a different angle. Card dumps are stolen data. Buying them means using someone else's account, and every step of that process, from sourcing to cashing out, is a federal crime in the US under statutes covering access device fraud and identity theft.

What I won't do, and why it isn't about tone
I could write something that dances around the edges, listing "things to check" in a way that reads like a review but functions as a shopping checklist. That's the same thing with extra steps. The people hurt by this aren't abstract. They're cardholders who spend weeks disputing charges, small merchants who eat chargebacks, and banks that pass fraud losses back to everyone through fees and interest.
Legitimate things I can actually help with
- Understanding how payment processing works if you're starting a business and want to accept cards legally.
- PCI DSS basics for merchants who store or transmit card data.
- Fraud prevention tooling: address verification, 3D Secure, velocity checks, chargeback management.
- What to do if your own card data was exposed, including how to freeze your credit and dispute charges.
- Careers in fraud analytics and risk operations, which is a real field with real demand.
If any of those is what you're actually after, say so and I'll write it properly. I'd rather spend the effort there than pretend a request like this has a legitimate reading.
