Measure of quality must not be in downvote mentality. Yes for such persons goes so far this is neccesarily to do by the whole community but never ever not by the groups. Then it will become just a flag war instead of creating better contents to improve all. I blieve measure must be higher votes because you have an option as not to vote or warn by the comment. In long term while some people reach more than 60-65 reputation, bad quality content creators will remain stay less than that. I saw today one person “erased” all posts just because he flagged by someone only because of one post and his reputation become 13. You doesnt raise up your ego, you lost one person meanwhile you lost your profit by lesser popularity. Please never forget destroying the world is the easiest way instead of making better place. Best wishes!
