From what I know bounty hunters are not required to submit KYC's as most of the time it is only for investors but then again every bounties have their own rules so you should ask this question on the assigned bounty manager.
Should that be too much for just a bounty program? KYC is a sensitive information. I do believe its only for Investors during an ICO. I would not dare to give my anonymity in return of a small token. (If they will actually pay and not just a Bogus program)
I think campaigns are requesting the KYC passage to make sure that the participant is not a US citizen.
