Scams are hard to get rid of, but experienced bounty managers may not recruit potential scam projects early in the review process. Let there be fewer bounty campaigns, but they will be of higher quality.
We don't blame the project that did the scam. We have to blame the stupid participants who continued to follow the scam campaign even though it was clear and was told by senior members that the project was a scam but forced to join.
There are bounty hunters who dont listen despite of the warnings, they just follow their own instinct without asking for others opinion. Well those bounty hunters who only look for rewards are partly to be blame why we cant get rid of scam projects. They dont do their own research and just blindly join without checking the projects's background.
Thats why we need to be careful when choosing a project because not all promising projects can end up as not scam.
