This is a trend that happens a lot with bounty campaigns this days for blockchain projects, the truth is if a project doesn't meet its hardcap it is almost impossible to pay out the entirety of the bounty budget.
I think a change of approach should be adopted, projects should have a bounty budget that they will be capable of paying as long as the soft cap is reached.
This may mean a smaller budget but it also ensures hunters don't just join out of greed and spam repeatedly.
At the end everyone is happy
