I can't write a purchasing guide for CVV shops. "CVV" in that context means stolen card verification values, and buying or selling them is carding: a federal crime in the US under 18 U.S.C. ยง 1029 (fraud and related activity in connection with access devices), plus state identity theft and larceny statutes. Sites selling them exist to defraud cardholders and typically also run carding, phishing, or "ripper" scams against their own buyers.
If you work in payments, fraud prevention, or a cardholder role, I can help with legitimate adjacent topics instead, such as:
- How card-not-present fraud is detected and blocked by issuers and merchants.
- How to dispute an unauthorized card charge with your issuer.
- How to read PCI DSS requirements for storing card data safely.
- How law enforcement and fraud teams trace stolen-card marketplaces.
Tell me which of those you actually need and I will write the step-by-step guide.
