I actually trust a casino more when they are quite clear on their policy around VPN's and as others have mentioned, they are prohibited in the T&C. They are actually protecting players in certain circumstances because gambling is banned in many countries which can come with some pretty harsh penalties. There can also be other reasons like difficulty in identifying bonus abusers, who jump around VPN's and can use a multitude of compromised identity documents out there to pretend to be other people. Maybe they will reconsider but allowing VPN's comes with a whole bunch of headaches, there are other casinos out there that allow them but they actually seem riskier.
