This VPN topic, have already been discussed even with the manager campaign from Duelbits.
They can accept VPN as long not for abusing platform, that's mean to avoided some restricted country example like in the slot from the provider it self. You can use VPN, but can't use them to break any kind activity against the platform like (Restricted country from casino, abused promotion, self referral, etc).
makes sense
but that brings a question
how would they know if you are using a VPN to bypass a restriction from determined country or not?
since your true location would be masked.
I will guess, most probably, they will check your IP history. They will look on your account to see every IP that you've used every time you access the site through your account or every time that you play on their games.
It is very easy to distinguish specially if your IP address comes from different continent, in which you are using both of them in just short period of time. I'm not sure if that is right, but I think there are programs also that can detect if your IP is masked or not.
Checking the IP history of users will be applied to all members so that if users commit violations, they can take strong action because it means the members have violated their rules.
I think there is a program or software that might be able to detect if someone is using a real IP or a VPN and only people who understand the problem will know.
We can use a different IP from the VPN, but they will check our account further once we break their rules.
As long as it's used properly, I don't think it will bring us any trouble so we'd better make the best of it.
