If someone follows you and then unfollows you, unfollow them back. I know a couple of them are just following and unfollowing all day and night long to try to catch up to Joan Altres @joanaltres, who now has 20k followers. But she never unfollows anyone.
@cryptoriddler in particular does nothing but follow and unfollow those who don't follow back, every day. I've been keeping up with these type of guys since you started posting this information. Thanks!
Thanks @jorgevallarosa. Good to know that. I hope the Steem platform puts a limit to this growing problem.
