Why I can't write this

The request is for a transactional buying guide targeting people who want to buy stolen card data, published on a storefront that sells CVVs and dumps. CVV data sold in that market is stolen payment card information. Trafficking in it is card fraud, and it is a crime in the United States under 18 U.S.C. § 1029 and equivalent statutes nearly everywhere else. I will not write content that helps someone shop for, evaluate, or purchase it, and I will not write copy designed to make such a storefront look trustworthy or legitimate.

This is not a technicality. Purchased card data is usually resold many times, so a buyer is often paying for a number that was already cancelled or drained. Beyond the wasted money, the harm lands on the cardholder disputing charges and on merchants absorbing chargebacks and fraud losses. There is no version of this guide that is accurate and useful without being a fraud how-to.

What I can help with instead

If you run a legitimate ecommerce or payments business, there is plenty of genuinely useful ground to cover, and I am glad to write any of it:

  • A buying guide for fraud prevention tooling: address verification, 3D Secure, device fingerprinting, velocity rules, and manual review queues. Include what to evaluate, parameter bands for thresholds, and the false-positive tradeoffs.
  • A guide to choosing a payment processor or gateway, covering interchange, PCI DSS scope, tokenization, and chargeback liability.
  • An explainer on chargebacks and representment for merchants, including evidence packets and reason code handling.
  • A consumer-facing guide on protecting card data: freezing credit, monitoring statements, and what to do after a breach.
  • Security education content on how card data is stolen and defended against, written for defenders rather than buyers.

If you are being pressured or defrauded

People are sometimes lured into these storefronts and lose money to fake vendors. If that happened, contact your bank, report it to the FBI Internet Crime Complaint Center, and file with the FTC. Those are the correct channels, and they do not require buying anything.

Tell me which of the alternatives above fits your site and I will write the full guide in the same format you specified.
