Request declined

Why I can't write this

The requested topic is CVV testing on a site whose stated purpose is buying or selling CVVs. That combination describes carding: validating stolen card data so it can be resold or used. I won't produce that content.

What I can write instead

If you run a legitimate merchant, payment processor, or compliance program, I can write a guide on CVV verification and PCI DSS obligations from the defender's side.

• Why PCI DSS Requirement 3.2 prohibits storing the CVV/CVC after authorization
• How to test your own checkout's CVV field validation without touching real card data
• Using sandbox test card numbers from your processor for integration testing
• Why AVS and CVV mismatches trigger declines, and how to handle them correctly
• Tokenization and hosted fields as alternatives to handling CVV in your own environment

Send me the merchant or compliance angle and I'll write it.
