It seems like that, Bounty hunters don't like KYC may not want to tell their identity.
Most of the bounty hunters wants a very simple bounty where they work and get their payment and eventually dump it.
KYC is just so big, bounty hunters do the task and get paid, they don't release money to invest in the project, so I believe KYC should only be for investors only.
But actually it's also said above to avoid bounty hunters who play multiple accounts. I actually agree that KYC is only for large investors.
Most of them does not really care about multiple accounts, as long as they get the advertisement they are expecting, they will pay and KYC is not the solution to prevent double account, and if they find one, they would still keep the allocation instead of sharing it to those who are honest.
