I Can't Write This Guide
The request is for a buying guide on a site whose stated niche is selling CVV numbers, framed around identifying CVV fraud signals. That combination is a fraud operation: CVV values are authentication data tied to payment cards, and guides that help readers source, validate, or evade detection on card data exist to support card-not-present crime and card testing. I won't produce that content in any format, including an informational guide, because the framing does not change what the material would be used for.
What I Can Help With Instead
If your actual goal is legitimate, there are adjacent topics I can write about in full:
- How merchants and payment processors detect card testing and card-not-present fraud, described from the defender's side.
- What CVV and CVV2 mean in payment security, and why storing them is prohibited under card network rules such as PCI DSS.
- Chargeback and dispute handling for small merchants, including evidence requirements and representment.
- Consumer-facing guidance on recognizing card fraud, freezing cards, and disputing unauthorized charges.
Tell me which of those fits and I will write it.
