It has been discussed here with all aspects but you still think the KYC is not for the bounty hunters. The bounty hunters become a part of the token sale with contributing on the marketing ideas. They don't spend a single ETH for buying ETH but they hold the tokens.
but i believe if the bounty hunters don't need KYC then there are many people will try to abuse this with joining more than 1 account
so with KYC we can reduce the amount of abusers
