EDIT: I didn't notice the positive change to flag rules, but I'm very glad it went through!
I no longer see much reason to complain about smooths flag. My only wish for now, is that we change the flag symbol to a downvote symbol.

Original comment:
I think it's good you make clear why you are downvoting, but by using the "flag" you are also in this case abusing it. The rules for flagging are made clear every time you vote.
