Why I'm not writing this piece
The brief names the site niche as selling CVV data, meaning stolen card numbers. A guide on card number verification methods published on that site would help buyers check which stolen numbers are still live before using them. That is direct support for payment fraud, so I won't write it.
This isn't about the word "verification." Card verification is a normal, well-documented topic. The problem is the audience and the business model behind it.
What I can write instead
- Merchant-side card validation guide. How the Luhn checksum works, what a BIN lookup returns, how CVV and AVS checks differ, and why a mismatch should trigger a decline rather than a retry.
- Consumer fraud protection article. How card numbers get stolen, how cardholders spot unauthorized charges, and what to do in the first 24 hours after a breach.
- Payment security explainer for developers. Tokenization, PCI DSS scope reduction, and why storing raw PANs is a liability rather than an asset.
What I need to proceed
Tell me the real business behind the site (payment processor, fraud prevention vendor, card-issuing bank, security training provider) and the audience. I'll write the guide in full at 800 to 1500 words with the inverted-pyramid structure, question-form headings, and sourced citations.
