Where do you read this? Duelbits allowed the use of VPN but not playing from restricted country. There’s many usecase of VPN and one of them is for privacy for purposes that’s why many user use it even if they don’t live on restricted country to access the casino. This is the case which Duelbits allowed the use of VPN.
But for those whose using VPN to bypass country restrictions will surely be penalized when caught by Duelbits team since this rules is clearly stated on the ToS. Allowing such players will put Duelbits license in jeopardy because they have legal obligations to restrict thise players.
IIRC, it was also on this thread and it was the rep that said that. That could have been the case and if my memory serves me right, that was what I can remember all about the usage of VPN but about a person that comes from a restricted area and try to use one, I can't remember but I guess you're right.
They have different categories for restricted regions which you can find
here but if you will ask them they will say not to use it but the main concern I was having was Gamblers from restricted region who use to bypass it when it's illegal in their country whether their intentions are good or bad the casino will have to comply with the rules.
Thanks for that clarification as I barely remember when I try to think of it. And for that gambler that's located in restricted country, much better not to proceed.
