Where is your evidence? But even if having evidence, why fake KYC? You have your money with a gambling site and you prefer to use fake KYC, what would happen last? It could bounce on you in a way you won't be favoured when the gambling site knows that you are manipulating with fake KYC.
Earlier like an year ago I did the same and they said it was not a problem and let me play so why is it a big problem now just because I have a big balance?
