And it's utterly useless, it might as well not be here. Especially when people like you abuse the system. You should only have given the dev a negative if you had traded with him and lost money. End of story.
THEN it will be trutly useless

Since the point is this is a scheme where someone will mathematically lose money while dev is stating the opposite. Trading with him is not related to the issue. He can even just make some fair trades AND try to run a ponzi. That will still make him a scammer.
Let's just stop, I read your concerns but I'm not convinced, pointless to go on.
