Yes, I total agree with you because bounty hunters are not customers they are just a promoter, moreover if kyc is should be done is should be done before registration of such project.
Bounty hunters are not customers but still, they are users of their coins and that's probably the purspose of asking for KYC even though that's still a stupid reason if you think about it. Every bounty should announce the requirement of a KYC before someone register as a promoter.
