Bounty manager together with the administration of the forum could to do it, but I doubt that they care.
No. They don't.
This issue was raised several times before, during the last 2-3 years. So I don't think that there is any point in beating the dead horse again. So ultimately, it is up to the bounty hunters. They need to decide whether they want to join such campaigns or not. In my case, I decided to quit the bounties almost two years ago. Unless the conditions are changed, I am not going to rejoin.
