Here's another way to put it:
A downvote means that I believe the rest of the community should have a greater say in reward pool distribution than than the user who upvoted haejin. This is my basic rationale for why I flag him. He is mindlessly and indiscriminately upvoted by a single individual who has never given any reason for doing so. It is my belief that Steemians as a whole show better discretion than that guy and therefore should be allotted a greater weight when it comes to reward pool distribution.
