Why I can't write this
A "CVV shop" sells stolen credit and debit card numbers, expiration dates, and security codes. Buying that data is card-not-present fraud regardless of how the transaction is framed, and a numbered walkthrough of the buying process is direct assistance to commit it. I won't produce that guide, and I won't produce a softened version of it dressed up as "advice and pitfalls."
CVV Shop Buying Guide Checklist
What I can write instead
- A consumer guide on protecting your own card details from skimming, phishing, and card-not-present fraud.
- How to spot and report a fake shopping site before you enter payment information.
- How chargebacks work for legitimate merchants and cardholders, and how to dispute an unauthorized charge.
- A compliance-focused breakdown of PCI DSS requirements for businesses that store or process card data.
Pick one of those and I'll write it to the same format you asked for.
