Nevermind the unfairness of reward pool distributions to meaningless comments holding no value like these, I'm more concerned that when you leave a tonne of comments with high payouts like these all over the place, it sends every wrong message to new users or curous investors considering STEEM. It already takes a fair amount of explaining and educating to convince newcomers that there is real value backing up the money they see being made on the platform. Encountering examples like this just make that job a lot harder.
Greenman, and others like him, would be better off considering how they can use their vote to incentivise behaviours that could help take increase the value of the token. Like supporting projects to encourage and help people give STEEM as a Christmas present to someone for the holidays (if I may ad some shameless self-promotion).
