I think it depends because there are members here regardless with the ranks can be trusted or they are the trusted managers to run a bounty campaign. If you know some, even if that manager was only low member in rank, the project would be still pretty good since trusted managers has the capability to run a good project.
In the event that the lower rank manager has been able to build a reputation then yes I could trust them to do a good job like they did before, but in a situation where we have lower rank with no past experience or reputation to manage a bounty, it would be difficult for me to join although I will have to consider the project as well and how dedicated the team are by observing their social media profiles
However, when legendary member manages a campaign, it is very easy for all to trust that campaign because of their rank and years of experience in the forum, it is assume such a high rank member would have done all necessary checks before accepting to manage a campaign, this is mere assumption though.
