In some of the threads I'm following lots of users mention the word "bounty campaign" or "bounty manager" which is a term I've never heard before. Is it something similar to a marketing campaign?
simply the person or individual who manages the campaign handles the distribution of payment to the group of people who are approved to wear the signature of a company who wants to advertise their company in this forum, instead of the company communicate with us they let the bounty manager answers our question, and make sure everything runs smoothly, they are the one who handles the marketing campaign to be exact.
So, as you said, the prize campaign or the prize manager actually means the same and true what colleague @akirasendo17 has clearly explained about the term gift manager which is often abbreviated as BM.
where he bridges between BH (Bounty Hunter) and Owner who has a project.
What is really important now is that BM is not getting a very crucial role so many owners leave the project and BM can't do anything.
BM should improve itself to be able to have a role from the Owner by giving the power to distribute coins and it must be allocated from the start so that there is no fraud.
