However, there's one thing I don’t understand: they made me go through KYC, asked for my documents, and even required a video where I had to state that I’m not associated with anyone else (I’m not a criminal, and I don’t even fully understand what they meant by that lol), only to then tell me, "You violated the T&Cs, so we’re not giving you anything."
But if that were true, they already knew it before verifying my documents.
i'm not sure about the video, but for KYC, i think they ask for it to verify your identity and geo and also to ban you permanently so you can't create new accounts.
they also need KYC to check against whatever third party fraud database they use, in case another casino has flagged your info there.
