I don't see how bounty scam will gradually go away because not all project team are sincere or have reputations to protect, this have make bounty hunters to have less respect in crypto space, new projects seek for bounty hunters to create awareness for their new projects but when it comes to paying they show their real colors.
The only solution to bounty scam is escrowed and this is only what good bounty platforms or bounty managers should introduce to atleast limit disappointments of not getting paid
Escrowing the funds could be the best solution but if the owners of the bounty campaign are holding the escrowed funds then we are facing the same problem, so we need a third party to escrow the funds but as long as bounty hunters keep accepting terrible work conditions for themselves this is never going to happen, I really think people need to stand up and defend themselves and if a bounty campaign does not offer some minimum conditions then people should not join it.
