For me, KYC procedure is not a good thing, and I do not want to send my KYC details to the person or organization I do not know really. The bad incident I have encountered is that most of the bounty campaigns or airdrops for which I have sent my KYC details did not provide me with my rewards. But there are many bounty campaigns which did not require KYC documents gave me good amount of rewards. KYC system is bad.
