That's the main problem that faced by almost all of the bounty participants. Some hunters were not even watching the awareness about how to do a good analyzation before try to participating in the any bounty.
So many members in here have already made various awareness about this but they didn't care about that.

That means if you can't dictate them to follow your awareness and then let them decide what they have taken like participated in the scam bounties.
The problem is people lack of DYOR.
