Regardless, I implore everyone to follow the terms and conditions of their casinos and to make sure that they complete their KYC from the beginning so that casinos will not use the excuse against them later.
This is bad advice. You should only complete KYC initially in casinos that mandatorily enforce it like Roobet etc. If it's not mandatory, you shouldn't submit your KYC information unless they request it later on.
It makes no difference when you submit your KYC as long as you are submitting accurate information without trying to fool the sites.
I do remember that there are some long discussions in regarding on that sudden KYC level 1 of Roobet beforehand on which tons of gamblers or the said site did really react out on such change but the fact that you are really just that only needing those informations like the basic ones without needing to send those documents then you are still able to play. KYC levels would increase basing up on the money that you are depositing or overall wager on which its not shocking for these kind of platforms considering that they are really that regulated or centralized then its not really that shocking at all.
It is really just that there are ones who are really that too mindful and allergy when it comes to KYC aspects and this is why they do really have this kind of reaction into it.
