A couple of times bounty manager is the one who was being blamed for the unsuccess projects. Not realizing that bounty managers are just doing their job whatever the owner wants him to do. And it is true that bounty participants are juat joining any ICO or any signature campaigns without further realizing that it is not worth to join for.
Being a bounty manager isn't an easy job. Reputations, good image, efforts and time are needed and I understand where OP is coming from all of his sentiments.
Bounty managers capability is of different types, few bounty managers on this forum cares about their reputations and they do research before approving a bounty project but some bounty managers are know for always introducing bad projects, I'm not going to mention names but this is true
although in good research, sometimes not all projects promoted by bounty managers can be successful. this also depends on market conditions and other factors. we cannot force and know the wishes of the bounty manager. we have to research the projects that we will support. and the decision is whether we want to join the campaign or not.
