Yes, because the more trusted a campaign manager, the more expensive the hire price will be, so a careless project can't easily do that. But that cannot be a benchmark, research on a project must be done even though it's running by campaign manager like that.
even some managers who have great trust are not enough, because they have also promoted a project scam, and have not paid, it is bad for the manager's good name. from now on, bounty managers should really think about choosing a good project.
Bounty managers sometimes also got victimized by those talented scammers, they've really good in talking but in the end of the day they will just screwed everything out and runaway with investors money, the bounty managers won't be able to do anything but to explain with the hunters what the real deal between the project.
