Since you ran into a problem, you might have had a glitch in the KYC system that caused you to be mistakenly caught by the casino. Although I am glad to hear that you have solved this problem now, but you must read the pledges carefully before submitting the KYC so that you don't make a mistake. Although I think submission of KYC only due to user error is a problem, but if you had given your KYC properly then it wouldn't have been a problem. Since your error has been caught by the casino, and it has been resolved by now, it is good for you that you submit carefully when doing KYC at other casinos in the future. Since you have found the solution in this casino, right now you can undoubtedly play here, and you can continue.
There’s no such thing as mistakenly ask for KYC because they have a reference and standard process to detect user that needs to do KYC. All users can be asked to undergo KYC on random basis without any further explanation from the casino but most of the time it’s because of how we play in the casino.
Yeah I believe no mistaken happen since its part of the system that something has been triggered that's why they ask this requirements to some users. And they must prepared for that since they can't escape this if they are dealing with large amount of money in this casino. So if they are doubting about this situation once the casino ask them to do so, then its more better to reach their support and discuss about why they had been asked this. But they have choices if they want to continue or not since if they don't like what has been asked then its up to them if they seek for other casino that doesn't require them to submit a KYC.
