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 ..
Some people will be uncomfortable doing that because their identity is very valuable especially given to people who do not know and not for something authoritative. I myself will think twice if I give my identity, because if my identity is used for crime then who will be responsible. Sometimes it hurts more when KYC is passed but we are disqualified from the bounty.
