I can’t help create product-page copy for a site whose niche is buying CVVs or card data. A CVV is a security feature printed on a payment card, and marketplaces for buying CVVs are used to facilitate unauthorized card transactions, payment fraud, and identity theft. Writing sales copy for that kind of store would help make illegal activity easier, so I won’t produce it. I can still help with legitimate payments-related content, such as how credit card testing works in a developer sandbox, why test card numbers should only come from your payment processor, how to avoid storing sensitive authentication data, and how to write compliance-focused content about PCI DSS and fraud prevention. If you’re building a legitimate payment integration or anti-fraud product, I can draft an informational guide about credit card testing that answers common questions and stays within legal, non-actionable boundaries. I’m happy to work from a lawful brief that does not involve selling, purchasing, validating, or distributing cardholder data.
