That will create ruckus to the one who is gambling with that account. A gambler that have borrowed identity just to get KYCed will surely run into problems.
We will never know when but if the time comes and that person who they borrowed document for verification isn't around and the casino asks for an additional doc, what could they do with that and if there is some hefty funds that are in there?
but now... do you really think so?
I mean, how often they will check KYCed accounts?
all the time or only after big wins?
I'm not sure...
I'm not going to say that this is justified because for me it only makes things more complicated for myself but for some people who do this they must also have their own views so they try to register and KYC with someone else's identity in order to benefit themselves.
My friend is like this where he did KYC with someone else's data because he thought that he really didn't want to be registered on a gambling site but still wanted to gamble on it. I can't prohibit it because in the end there is already a decision between one and the other so everything that is done in the end depends on the point of view and there will definitely be pros and cons about this.
The first person would easily go away with whatever he's got because he's got no obligation as it's not his identity. Whilst the latter, there's a sense of responsibility because of using his own identity.
