But its understandable right? As you said mostly when there is sudden changes in the activity of an account will trigger the security system of a casino which may put the account on hold until the further process comes officially,
Yes, understandable. As they're also just following the head for the rules set to them to ask their players for verifications. It's the same as the exchanges, the mandatory verification and compliance for the kyc.
yes its bit annoying but also it can save someone's money if the account accessed without authorisation from the actual user.
True. If ever there's an unauthorized login and access from someone that the database isn't recognized, the alarm will be triggered and they have to halt any transaction from that access.
