KYC is protection from multi-accounts, if you can prove your identity, and others can not, then you will get more payments!
I do not see it as you think, many bounty hunters do not pass kyc but their money is not divided for those who pass the kyc. It is managed by bounty manager that can keep airdrop or other bounty programs. I think the bounty should be kyc before the start, the hunters pass the kyc will earn more.
