The new reputation system makes it even harder to do what you are suggesting. Let's say someone writes an 'average' post, and a ton of people upvote it because it is trending and they want to get a good curation bonus. Then a person with high SP comes along and decides it is too high because everyone was colluding. It wasn't a bad post or anything - it is just overvalued. If they flag/downvote that person's post to lower the amount it gets paid, that person's reputation is affected too. Most likely the person who wrote the post didn't do anything intentionally wrong or bad to make the excessive upvotes happen. Yet their reputation score is penalized by the person who downvoted/flagged their content.
