FYI, you won't know in detail what the bounty managers do behind the bounties. I know some bounty managers, the did very hard efforts to pay the bounty hunters. They worked hard since offering the team projects to have bounties, then share the bounties to hunters. Then, they struggle to give proper payments to the bounty hunters. But yes, most bounty hunters don't care about this, they only think about their payments to get as quick as possible.
Once the bounty managers can bring good bounties paying hunters with a good amount of money, then surely increases their reputation.
Moreover, if the bounty managers can manage the bounties well such as finish the spreadsheet fast and distribute the payment on time. You don't need to remind them, it directly gives big impacts.
