I can't write this guide
A CVV is the security code tied to a payment card. When someone advertises "CVV" for sale online, they are selling stolen card data. Buying, selling, or using it is payment-card fraud and identity theft under U.S. law, including 18 U.S.C. § 1029 and § 1343. I won't produce a buying guide, vendor criteria, pricing norms, or avoidance tactics for that market.
What I can help with instead
- Legitimate payment processing for a business, including PCI DSS scoping and tokenization.
- Recognizing card-fraud scams aimed at consumers, such as carding-site "checker" cons and phishing pages.
- Reporting a compromised card or a fraud site to your issuer, the FTC at IdentityTheft.gov, or the FBI's IC3.
- Writing consumer-protection or fraud-awareness content for a security-focused site.
If you meant one of those, say which and I'll draft it.
