If OP didn't win there would be no problem. They would have taken his deposits without even pondering to do KYC, since it would not be good for business banning a profitable player. Sure it's OP's own fault but it's also the system which is fxxked up.
When will casinos finally make KYC upon registration, this would end all this nonsense.
But I guess they don't want to because this scheme freerolling players wouldn't work anymore, won't it.
They required kyc upon registration, i completed it with my dutch documents and it got accepted by their team.
I was able to deposit and gamble as much as i wanted to, only on a big withdrawal they banned me and cancelled the withdrawal.
