If we will have everyone to blame, it will exert countless effort to determine who should be blame, some bounty hunters are just bot, they don't read, what they care is that they just do their job, so it's nice if it will start from the bounty managers since mostly the relationship is only between the bounty manager and the team, as a bounty hunter we can't approach the project team as they will just say they have already appoint something to do the job.
It would mean shifting the blame again on the manager.
They already receive flak from hunters who are literally illiterate enough to not read every instruction and act like complete baboons. Even then the managers are kind enough to help them out.
This is in fact a very complicated situation if seen with a serious vision. We cannot rule out the fact that even most project owners are also frustrated on the finances received from the offering. Thus their ghosting to pay out participants and therefore the constant spamming of PMs to the manager from hunters.
I dont see any way out from this except redesigning or removing the entire "bounty" system.
