they're a bunch of content nazis who have zero talent so they think they make themselves useful by wrecking other peoples work , just ignore them, they go away after a while , make sure you never vote them or their cronies for witness, its the filth of steem , some bidbots take your money and send it to them if you're on their blacklist as if that is an excuse or something, its an old cartel from the first days of steemit, they're losing ground as no one really like them but a few of the upper class and there's nothing you can do against being downvoted. It's like the feudal lords of old. Just sit it out, they'll go away
