We started a bounty program at the time and paid the manager weekly for it. After we noticed that the costs did not justify the benefit, we stopped the bounty program and did not make any further payments. It is very difficult to successfully do marketing for new projects because there are so many scammers.
Both bounty managers you hired are indeed scammers as they have the habit of enrolling multiple accounts under their control into the same bounty campaigns. This means that the quality of their output will be reduced, if they are even doing anything at all.
Please explain to us why you call Ava Area a scam?!
To be fair to your project, neither OP nor anyone presented any evidence that it is a scam, and I don't really know why they said that.
