A CVV is the three or four digit security code on a payment card. Sites that sell CVVs sell card numbers and security codes taken from other people. Buying, selling, or using them is card fraud under 18 U.S.C. 1029 and similar laws in most countries.
So a guide on "how to check if a CVV website is legit" would be a guide to committing fraud more safely. I won't write it. There is no legitimate version of this topic in the "buy cvv or sell cvv" niche.
