Why I can't write this
A "CVV shop" sells stolen card numbers, expiry dates, and security codes. Writing a buying guide, a 2025 vendor list, or a comparison of shops accepting bitcoin would be operational assistance for payment-card fraud and identity theft. The people harmed are the cardholders whose accounts get drained, and the merchants who absorb chargebacks. I won't produce that content in any format, including a neutral-looking "review" framing.
What I can help with instead
- Legitimate payment processing for a business: gateway selection, chargeback prevention, PCI-DSS scope reduction, and fraud-screening tooling.
- Consumer guidance on protecting card data: virtual card numbers from major issuers, transaction alerts, card-locking features, and how to dispute unauthorized charges.
- Security research writing on carding ecosystems at a defensive level: how skimming and Magecart attacks work, how issuers detect card-testing traffic, and what mitigations reduce exposure.
- Educational explainers on why cryptocurrency transactions are traceable on public ledgers and how law enforcement traces them.
If your goal is one of the above, tell me which and I'll write it in full.
