I didn't know what KYC stand for, I initially tought it was something like "know your customer so you can provide better service" or something like a marketing deal or something

Apparently it is not. Well this sounds too much like George Orwell's 1984, why do you need to "know your customer" in this sense, I am fine with facebook collecting info about me so it can send me advertisement but collecting info so you can share with goverment doesn't sound that good, I am fine with advertisers, not so much fan of goverments.
Knowing this customer I think it's like a system of leaders, located under their system and they can look into the track. But there are many factors that can hardly explain "knowing your customer" what is their purpose? Need?
However, no matter what happens when they believe in their leader.
