I honestly don’t know what’s your issue here but your statement here is an obviously attack against Duelbits since you are using their security procedure as some sort negative feature of the casino which you can experience too on other casino with same circumstances becoming of AML policy.
Money laundering is more regulated globally so casinos are not exceptions but I really believe big casinos with proved business, good reputation don't pull their KYC and AML card if they don't detect any suspicious activity from an account. Their casino reputation is more important than investigating a user without solid proof and take risk of damage on their reputation that takes many time like years to build up.
