In case anyone is wondering how reddit got ruined, this is an excellent rundown from u/ready-ignite

They are going to try the exact same thing with witnesses on the steem blockchain, they do NOT want blockchain tech to be able to record all their activity and for people like me to be able to legally call them out without censorship. That is exactly their plan, buy enough SP and upvote each other to the point where they can vote each other in as witnesses, then they will bring the whole thing crashing down.
