Bounty managers take money for managing the bounty campaigns, at the end they really do not care about the legitimacy of the promoted project.
They have stated in the bounty thread that they are not responsible to any losses you can get by joining these campaigns because they act as a campaign manager only. Although, it could affect their trust quality on their accounts. Would rather to be a legit person and try everything on board you know.
Only managers that managing more campaigns care more about the quality because they want to make a brand, that would bring a trust for future bounty campaigns.
This also means they can accept whatever the fuck projects they want as long as it gives them big money.
