I full heartedly agree with your comment! They are a cancer to the Steem network! I have been terrorized also by Hive account@mack-bot Hive account@steemcleaners @Spaminator and company. I hope these cancerous parasites that indiscriminately downvote accounts will one day be terminated by a whale and the Steemian community.
Unfortunately they do not look at individual posts, but indiscriminately downvote the whole account! I believe these Gestapo tactics are like killing an ant with a sledge hammer!
Their tactics are no way to police Steem. The police does not shoot people, they try to help the community.
