What i know, KYC means Know Your Customer ! Bounty hunters are there to Support ICO Project to spread the word about the project .. BUT as soon as the Project manager mention KYC then many Hunter run away ! Why? Is it because people don't want review their identity for security reason or people are joining campaign with bot software ..
Maybe because they don't have any valid id's or it could be they are criminal or what. But for me as a bounty hunters its fine for me to submit it according to their requirements. There's nothing wrong with when it comes to that matter. And KYC is top prevent cheaters and scammer something like that.
