I think only a few number of bounty managers actually care about the participants, some bounty managers just go ahead to manage any project that comes their way, not minding if its going to be profitable for the bounty hunters or not.
Professional bounty managers will only handle potential projects and it really analyzes like an investor before investing in one. However, at the moment their current campaign seems inactive and bounty hunters will be willing to quit other campaigns if they have presented a new campaign.
