Of course it is so. When you are just playing with $10-$20 it is not a problem but when it is a business - you have to analyze different casinos and their prohibitions. Or it is possible to get ban with big deposit. It is possible that some casinos will be waiting until your deposit becomes big and only after that they will ban account.
This looks trap, if casinos do that trick, better to avoid them and to do not register and play even 1 cent. I don't know why they bypass it on the beginning, if the user breaks the rules of VPN, it's better to ban him at the beginning before continuing to make any big winnings. I still don't know the rules of DNS, because I never heard the specific rule about that.
Indeed and even with a small deposit, it's always possible for us to win big but unfortunately it will only be forfeited because of their rules. I agree that they better make this rule clearer so that we can back out before the unfortunate event happen. you are wondering why some can access a blocked site?
I think the owners didn't know this either but I think it's easier for them to find this out once that player make a withdrawal or even deposits, and that is the time they will question them. It's also the fault of the player. They already know that gambling is already blocked on their country but they still find a way to access it. They don't have the right to complain.
