The project bounty manager should have at least checked the background of the campaign first. Isn't downpayment for the bounty manager possible? That should make the scam project move away from the bounty manager.
It is not as easy as you think, i believe no bm would deliberately want to promote a project of scammers, the bm must have done the normal background checking no doubt and the team appears to be trusted only to later discover they are not,
when things like this happen, the first thing many will assume is the bm did not do a proper check but we shouldn't forget that a project can turned scam or rug pull when you list expect, no project will agree to be scammers until they turned out to be one.
I agree. I also think the bounty manager checked the project first because it is his/her time that is at stake here. But what I was saying is that isn't it possible that the project pays a downpayment first or to escrow the fund first to be paid to the bounty manager? This way the bounty manager can see that the project is serious.
