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 ..
most of them didnt want their identity spreaded.moreover just for reward that the value still uncertain.privacy more important for them maybe.but if there is another reason i dont know about it.
Yes, I agree with you, maybe this is the right reason for them to get everything, because the identity in my opinion is more important to prevent it from being misused, so for some people it's not easy to give up their identity just to get the token prize they gave.
