Sometimes, we tend to break the TOS just to enjoy gambling despite the restrictions but as we take the risk, we should also keep in mind that our funds aren't in a safe place. 1500 is still a huge amount but to be honest, it would be hard for you to recover it. VPNs aren't that safe these days.
There are safer ways to gamble but its our nature to choose what is more risky because the experience that we can feel there is in a different level and finally you are in a situation that you are expecting. It is now time for you to pay the price or to face your consequences. Our funds is already in danger when we gamble and how much more if we gamble in a much riskier place or in a riskier way? 1.5k can be huge for you but maybe it is not that big for him.
It is hard to recover it on his own, that is why he is here asking for advises if he can do something to get the cash. VPNs are safe as long as its from a trusted brand but i think what is not safe is when you use it on a restricted site.
