"There are people who's only goal is to publish low-quality posts and buy big upvotes for them, in hopes that they get upvoted by people who don't take the time to actually view those posts."
And the even more sad fact is that they are right.
Or at least they are right in some level.
There are a lot of people, who don't even read the posts, but they often write (spam or spam-like) comments, and they upvote their own meaningless comments INSTEAD of the original post.
They are completely ignore the original posts.
Steemit is a good social experiment.
