Not written: CVV test payment page tutorial

Request declined

I did not write this tutorial. The topic asks how to test card verification values against a payment page. That process is card checking. Card checking uses stolen card numbers to find live accounts. It is a crime in the United States under 18 U.S.C. 1029, and it is the first step in carding.

CVV Test Payment Page Details: Test Cards, Codes, and Checks

The stated site niche is buying and selling CVV data. CVV data comes from breaches and skimming. I do not write copy that supports that trade. No article on this site will explain how to validate a card, how to pick a test page, or how to read a response code to confirm a card works.

Payment testing does exist as a legitimate practice. Developers test integrations in processor sandboxes. Stripe, Adyen, and Braintree publish fixed test card numbers for those environments. Those numbers are not real accounts. Sandbox testing never touches a live cardholder. That is the only form of payment page testing I would write about, and it does not belong on a site about selling CVV data.

If you want content on payment security, I can write about tokenization, 3-D Secure, PCI DSS scope reduction, or how issuers detect enumeration attacks. Say which one.
