Oh I have seen it in action. iflagrewards and mack-bot are in my opinion a problem not a solution. There are very very few places where an individual is crucified over and over and over again for the same mistake. No flag should be allowed with out a person commenting on why it was flagged, that is the first issue with flags, if you an not give a justification for it regardless of how lame the justification is, the flag should not be allowed to stand. The blanket party flagging that goes on is useless. There was no justification for any of your comments to be flagged in this stream. there was no reason for sift666 comments on another stream to be flagged other than someone did not like his responses to bot style suck-up give me a vote I left a comment comments.
Each and every flag needs justification behind it, and it need to be justifying what is being flagged, not some post or action yesterday or a year ago, but the comment being flagged.
