I think KYC is not that bad. The main purpose of it is for added security and protection not only to your account but specially to the exchange itself. So they could prevent from being used, intentionally or unintentionally, by criminal elements or money laundering activities.
Nowadays all the data's are collect and sell it on private companies so many peoples are not ready to join KYC exchanges but KYC is increase the security level most of the investors are understand why they ask the KYC verification.
It is limit the scammer so we should believe 100 percentage on KYC exchange.
