Looks like he updated the bounty topic with some explanation regarding the bounty campaign issues and according to him, he also got scammed. It is a convenient excuse (maybe bounty hunters should check it in the project's TG group) but I wouldn't be surprised that altcoin project refused to pay the bounty when they saw the results. I am sure that bounty managers tell them bunch of crap about effectiveness of bounty campaign in order to sell it, and in the end when clients take a look at the horrendous quality of articles and videos and realize that they got scammed, they refuse to pay.
This is not the first time that this bounty manager has been accused of unethical conduct. It seems to me that he really does not care what projects he promotes or what members he chooses for his campaigns. No wonder he does not want to answer these accusations; as long as the business goes on, who really cares?
These projects' owners aren't very bright either, seeing as how most of them are only interested in making a quick buck from the bounty campaigns and their project's ICO, and not in the quality of work that is being done. They do not care about the quality of their own product, let alone that of a bounty campaign and its participants; and they are certainly not concerned with how many people they burn along the way.
