I can't help with this. A review of "CVV shops" would involve comparing and recommending services that traffic in stolen payment card data, which is card fraud and identity theft under laws such as 18 U.S.C. § 1029 in the US and equivalent statutes elsewhere. I won't research, rank, or write content that helps people find, evaluate, or use those services.
If you're writing for a payments or ecommerce audience, there are legitimate adjacent topics I can help with: how card-not-present fraud detection works, what PCI DSS requires of merchants, how tokenization and 3-D Secure change checkout risk, or how to compare mainstream payment processors and fraud-prevention tools. If you were targeted by card fraud, the practical step is to contact your card issuer and report it to the FTC at reportfraud.ftc.gov or your national consumer protection body.
