it's one thing to flag because something is harmful within the post. Although "harmful to society" is often in the eye of the beholder and whose society.. the beholder or the writer. The difference could be cultural.

It is still quite another to flag simply because the writer is getting more than that person thinks they should. Obviously other readers have already shared as they see fit, who is anyone else to decide they want to take some of that away? Still comes back to jealousy or envy.
