So in essence you are saying the case of where the gamblers are being confiscated are unreal if only the gambler breaks the rules of the casino? So what if one of the rules of the casino is gamblers from certain or withdrawal to certain users on that country isn't allow and then you were asked to verify KYC maybe due to the amount of funds you won and want to withdraw, do you think the casino won't make a stand on seeing that your KYC verification is showing a region which is prohibited by the casino. except only if ofcourse the casino allows VPN.
Yes what you said is unreal that casinos will confiscate user's fund just because the users come from country where gambling is illegal while the casino itself is accepting players from that country.
If what you said is real, there should be so many gamblers from my country who get their funds confiscated because of the reason you said before, but the fact is that I have never heard it even once.
Your example is simply not the case, so stick to the specific case where gamblers come from country where gambling is prohibited but casino accept players from that country.
If a casino accept those players who come from countries where gambling is prohibited, the casino has no right to confiscate user's fund, if casino do it then it can be said as a scam casino because they put a trap by allowing those players to play but using a reason which is not on their terms to confiscate user's fund.
When players breaking the law of the country, the casino has no right to confiscate user's fund unless the casino has a clear written terms such as "we have the right to block or confiscate user's fund if we know that the users come from countries where gambling is illegal".
