It is highly unlikely for scams like these will go away. Especially now that there are more hunters out there that are willing to take up job because of the pandemic. Overall i just feel bad for hunters that spent their time on these scams.
Many hunters that will not do research if they are working on scammers and many developers who can create a project that looks like a good project, they have no problem with promoters since they already have a lot fo bounty hunters who will work for them in exchange for free pennies or none at all, in fact, these scammers are scamming bounty hunters and investors.
