There are lots of member busy on catching those who abused the principles at Scam Accusations thread.
Most of those cheaters have been caught and reported on Reputation thread, not scam accusation. Scam accusation is needed when the project turned to scam and ran away with their ICO/IEO/Defi money.
I don't want to blame the bounty manager because a project will be a success or a failure there is nothing for the bounty manager to do.
Managers MUST do some little research first before he accepting the project they want managed. At least, escrow the bounty funds to them or trusted escrower.
