My own opinion on this, bounty manager had a great responsibility in all boundaries that he handles.. if it is not intentional, then he should find out sooner once the ICO started since it's job is "to know all about the project that he manage". And if he's not involved, then he himself should stop the craps and spread the news to bounty hunters.. So that, they cannot victim or scam..
I considered myself as a bounty hunter (when I was not demoted from jurnior member to newbie) and it is not an easy job.. Though it is my part to think, research and decide, sometimes when I see majority join and if you see that there's a lot of investors, then you will be encouraged to join the bounty..
