To my understanding, KYC simply means "Know your customer". Investors(customers) who participate in ICO are made to go through KYC process before they are even allowed to purchase their tokens. On the other hand, Bounty hunters are just "part time workers" of the project and not customers. Even if they will be made to go through a KYC process, it should be before they start working and not after. Waiting for them to finish working for the project and refusing to pay them because they failed to pass KYC afterwards is a total cheat.
The main idea of the KYC procedure is to exclude the participation of fraudsters and multi-accounts. Fraudsters and deceivers are not only among investors, but also among bounty hunters
strongly agree with your statement about multiple accounts because many bounty hunters use many accounts, it's hard to prove it, because everything with their own honesty, and holding Kyc is the first gateway to honesty, bounty hunters and investors.
One of the main objectives of KYC for bounty hunters is to avoid using multiple accounts. And the other goal is indeed for the terms of the project. If we do not want to do the copy of the project. So don't ever participate in brand bounty programs. Easy to do.
