So I’m wondering, is this really a legal safeguard, or are they just using it as their own policy to forfeit players’ winnings?
This is actually a serious concern. Most of us might not have reached that level yet, but what if one day we do hit it big and end up facing the same situation?
Today it is normally. I think that it is a way to steal our money, but mostly you accepted the ToS and their there is something like "casino can KYC you anytime they decide".
And of course it is accident. After your big win.*sarcasm* I created in different casinos accounts(some times few accounts in one casino) and always i was KYCed after several win in a row of after big win.
