Request declined
I cannot write a buying guide for CVV dumps. "Dumps" in that market means track data skimmed from payment cards. Buying, selling, or using it is payment card fraud under 18 U.S.C. 1029 in the United States, and comparable statutes elsewhere.
A guide on shops, prices, escrow, or vendor vetting would be instructions for a crime. That is true even when the request is framed as security research or as a buying guide with pitfalls.
What I can write instead
- How card-not-present fraud works at the network level, and why chip and tokenization reduce it.
- How issuers score card-not-present transactions and what merchants see in an authorization response.
- Steps a cardholder takes after a breach: freeze, reissue, dispute, monitor.
Tell me which of these you want and I will write it.
