Only fools would do that. Some might be tempted by the payment offered for KYC, but it's a significant risk, considering that others could potentially commit fraud or cheating within the casino. If investigated further, the risks are far greater than that.
And for those who do it, soliciting other people's services is also vulnerable, considering that if you win big at the casino and the casino asks for re-verification, it can be very difficult to withdraw funds, as many casinos will do that.
