There are two different categories for reasons to flag:
- something wrong was done by the author
- the author got too much rewards
Now let us leave aside the debate on whether one should flagging based on too many rewards. To flag a post that has done too well according to some, will effect an author's reputation score iff the one who flags has a higher reputation score. If we had a low rep account that could down vote for us, then we could use that account to remove rewards without affecting the reputation of the author.
What do you think?
