It will be interesting to see the results, I still believe it will be the Stanford Power experiment all over again with the jailers and the prisoners, or the blue eyes brown eyes, or any of the other test where people are given power over other people. I do not you tube or facebook, but I hear about the downvotes and abuse there, I have seen on a daily basis the abuse of downvotes here on steem. People will take advantage of it and the abuse will intensify. We already have McCarthy era style blacklist, and the abusers meaning well can say what ever they want but when you down vote a comment that was pertinent to the post and in line with other comments, that is abusive behavior no matter how they want to justify the action. An individual should not be punished for life unless they committed a capital crime. Most civilized groups of people believe that tenant, the flaggers on steem do not.
