It is not easy for Bounty managers to predict scam. It is better to talk to Bounty manager ad make a solution by which you can contact team of ICO , if it is scam then take help of bounty manager and raise voice against ICO team.
I agree. The managers themselves are just under the employ and control of the developers of these ICOs or projects, therefore, they cannot also tell if it is a scam or a would be failure in the long run. Also, if a project turns out to be a scam, they will be part of the victimized public, because in a sense, they too only gambled in the project just like everyone else who joined.
