Here's an idea, when a post gets flagged, then it can be sent to a Flag Feed, a Flag Tag, a Flag Community, or whatever we want to call the place, then people can view it and vote yes or no to agree or disagree with the flag. So, if a post is flagged, then freeze potential rewards for that post for a month while it is pending in trial, people can vote and if the people vote not to have the post flagged, then have a way to punish the flagger. But if people agree that the post should be flagged, then find an appropriate punishment for the publisher of the flagged post.
