This is really the main concern on why casinos like Rollbit discourage to use VPN since they don't want people to violate this matter.
I don't also think that this issue has something to do with VPN usage. But rather maybe Rollbit detect something and think about there's multi accounting happened that's why that issue exist. If it happen that someone stole his information then I guess that might give him a problem, especially that he can use it on other site that will ask a KYC verification. But let see how this issue end up and looking forward to see good action and he confirm that everything is fine after Rollbit solve his issue.
Since Rollbit is one of the official casinos that has clear legality, they have a security system to detect suspicious activity, such as the use of multiple accounts from one device or inconsistent locations due to VPN use. And although the use of VPN is not always the main cause, to anticipate abuse, such as the creation of multiple accounts or identity theft, the use of VPNs must be prohibited by the casino.
So I agree that the best solution is to wait for the verification process from Rollbit and avoid using VPN when accessing this kind of site if it is not really necessary.
Why would be that trying out to access or make use of VPN if you are prohibited in the first place? On the moment that you do try out to access the site and found out that you do have those kind of errors
then better not to pursue on making use of VPN on which pretty sure that your country is prohibited to access the site. So its better to find yourself with other platforms on which pretty sure that there are tons of options out there and you wont be needing up to proceed and making use of VPN and later on whining on why your account has been blocked.
Also, reading up sites terms and conditions isnt that that costing you an arm and leg. When it comes to bonuses then abuse is there but since these are businesses then they do know
on what they should gonna do on detecting out those abusers.
For security reason since VPN is not all about bypassing restrictions, but because of many abuse happened for example multi accounting and bypassing restrictions the casino flagged some users that's why some people encounter an issue with it.
That's why as much as we can we should avoid using VPN. If they think they are not in comfortable places better not to gamble, they could just do it when they think everything is fine and they don't need to worry about their safety. Also other should not think about bypassing a restriction since for sure the casino have ways to detect their actions done.
