As a follow up for the previous topic and as this one is more clear about the issue.
Certain casino's based in Costa Rica, Curacao, Cyprus and some MGA based casinos do not debit casino transactions under the name of their casino (or managing company) but use through their payment processors different names and more important different category codes so banks will not block these transactions to protect the consumer from gambling too much. A while ago Reuters also figured this out: https://www.reuters.com/article/technology/exclusive-fake-online-stores-reveal-gamblers-shadow-banking-system-idUSKBN19D137/
This is a sad thing as it can dupe many consumers or addicted players in gambling too much or losing more money then intended.
In some countries (including mine The Netherlands) the casinos that do such things are in all cases illegal based casinos which are in 95% aware of this but simply do not care. For players this is of course an unfortunate situation, but as the merchants are not from the casino this also gives possibilities.
Several merchant names have been mentioned in the previous topic and I hope that with this thread which is more clear to continue so other users can find it easier.
