Very nice topic indeed this is. I also find bounty hunters having heard mentality. Most of all bounty hunters are bots which get enrolled in bounty campaigns by a single person.
These bots are not giving chances for normal people to earn in bounty campaigns. if you find such accounts you need to inform the bounty manager
I am hearing about this bots for the first time and I think if that exists it will be very difficult for them to do the promo like normal human beings can do. It also means that bounty hunter are also manipulating bounty campaign too. We have many project that was promoted here and end as scam and that is the reasons I adopted the Idea in the op.
