It drives me crazy when new people on the platform spam me with "follow for follow" or "upvote for upvote" I immediately explain to them this isn't that type of platform and it will hurt them more than help them. I think most people pick that crap up from instagram. I don't use that platform but my fiance complains about it all the time. People need to understand it is not about quantity on steemit, its about quality, and that applies for not only followers but also posts and comments.
At the same time I'm not to quick to delete people either, I understand that not everyone is full time or even part time but they still have good content and reply when they are on. That is why I go through my followers list once every month or two, and I am rather picky about who I add in the first place ;)
Good article, I hope a lot of new people read this.
