I flagged you because you were advocating the abuse of the down vote function - exactly the matter at issue in this post today. You were telling people to downvote based on the earnings of posts in Trending rather than for any steemit abuse like plagiarism. That is flagging based on jealousy.
But you are right. If my reasons for flagging had been stated clearly in a response - then readers could evaluate for themselves my reason for flagging. That is the proposal that I am advocating.
