I don't really believe that bounty campaigns runs by a newbie ranked bounty managers is legit. There are times that those bounties are being created just to gain followers on their social media accounts and add more people on their channels or groups, and later they will change the name of those pages and channels to their personal accounts once they had much followers. But I do believe if the forum username is the project itself even if it is still a newbie.
The very chance that the project manager is under management of the team itself, if the newbie account was name under the project very likely that it's the team responsibilities whatever happened with the bounty.
Incase something happened, hunters can blamed the manager and it will reflect to the project itself.
It won't affect you much if you manage to do your research, investigate and follow first the development
of every project that you are targeting, success of receiving rewards depends from the success of the entire project.
