This is the difference between good bounty managers and ordinary ones. A good one will hire a person, for a small fee, who will check all social network participants for the quality of the content and the quality of the services provided.
A good project does not need useless marketing; it needs a precise and high-quality presentation of itself through bounty hunters.
Is there really a way to check the quality of the work of the bounty hunter if their only task is to like or share in social media? I don't think that there is a need for that quality check. What they need is to limit their bounty participants to at least give them enough opportunity to receive more rewards.
Of course there is. But only in the creative field. Repost companies are completely mechanical, no one adds anything new, they just copy. While YouTube or articles or other creative activities are very easy to check for quality, this is exactly the field that bounty managers should work with in the first place. It is in this way that it will be possible to weed out poor-quality content that will provoke a decrease in the number of participants in the bounty.
