Everyone decides for himself, he wants to participate in the bounty companies, which require to pass KYC. I think that there are no such managers who speak about passing KYC at the end.
Recently, I took part in the bounty, in which the developers made changes, and all the hunters should follow the KYC procedure in the companys personal account using the wallet on the platform of this project. However, half of the weekly payments have already been made on the ERC-20.
