I monitored the cards in at least two stores. In one store, 240 out of 300 purchased cards were listed for sale, and in the other store, the number was 149. This means that after being sold, the cards are then listed in other stores in bulk. At a scale of several thousand cards per day, this adds up to a lot of money—about \( \approx \) $1.6 per card.
I only checked those two stores where this number of cards was present. God knows how many other stores are listing them as well. A single card gets sold to dozens of people— even if everyone tests it with the checker, the card may show as valid/safe, but there’s still a security problem.
Of course, I also need to mention this: when purchasing, the shop owner told me to buy with full confidence, because our cards are not sold anywhere else; but after the purchase, he says there might be leakage/data leaks of the cards. How interesting.
Proving that the admin himself sells the cards in bulk to multiple stores isn’t that difficult, because I selected these cards from different databases—at least from 20 different databases. So how do they all end up at another store?
Unless the seller(s) gather the cards outside of his store, share/synchronize the databases they were given, and in the end create a shared database that they then list in other stores?
Of course, you’re clever—you can scam anywhere—but not in the “scammer syndicate”!
This is a place where laws are written down. You can only be honest here and enjoy fair business.
If these kinds of violations aren’t stopped, then every store will start selling those cards again to dozens of people.
