I’m wondering why some casino discouraged the full use of VPN while others fully support the use of it.
even if a casino claims to be VPN friendly, i wouldn't play there if my country is blocked. they can change their policy at any time, and you would end up fucked.
And there is the catch. They are supposed to promote the VPN but in reality, they are setting a net (of protection or trap, take your pick) from which you cannot escape and you will always depend on their judgment and appetite. They profit from the advertising and the hype that is caused, they force you to go through the KYK for withdrawal (at some point they all do it) and if they consider you shady, they simply change the ToS. It's better not to use a VPN, you get into trouble from the start.
