I think there is no sane representative to suggest the use of VPN when it is restricted on their TOS to bypass the geo-restriction. It is really suspicious if someone from the representative suggests breaching their contract and I believe this is the tactic of shady casinos to entice users from the banned country then deprived them of the winnings whenever they hit big.
They should never officially advice their users to bypass ToS and geolocation restrictions through VPN. It leads to potential big problems for user accounts and funds in future.
The more acceptable approach is building up mirror sites that can be accessed by people who are from counties that consider gambling as illegal. Users have to be responsible for their actions, not against the casino's ToS but the national regulation and ban against gambling.
Its like they are potentially giving a problem to their player if they advise to do that. Also I don't think there's a legit will suggest that since they might also get a problem in that situation.
So what's really better here for anyone to follow hat has been written on the TOS so that they won't encounter any issue here. If they know that they are been geo restricted better follow and just move to other casino since this is better option to do.
Read lots of issue about bypassing and for sure they won't like to experience that problem.
