To my understanding, KYC simply means "Know your customer". Investors(customers) who participate in ICO are made to go through KYC process before they are even allowed to purchase their tokens. On the other hand, Bounty hunters are just "part time workers" of the project and not customers. Even if they will be made to go through a KYC process, it should be before they start working and not after. Waiting for them to finish working for the project and refusing to pay them because they failed to pass KYC afterwards is a total cheat.
Of course now a lot of projects introduces kyc to deceive many people , but I think that some projects that are well collected during the ico and then you can go through their kyc to get tokens!
KYC is a decent way to know your customer ( also for those participant of the bounty program ), don't put a negative way about the KYC. If you don't want it, ask first before participating on that project, if they have... you are free to leave or walk away on it. KYC is not created for a wrong doing of others, and that is the real thing.
