Some are just too greedy they forgot that others really matters. The crypto world is a good example. Either Positive or Bad greed, they are all greed.. Some will drop a comment a post, they won't upvote the post but they will upvote their own comment.
Exactly! In the end that will only be bad for them! People won't like them in the long run and steemit is not only a blogging platform but also a social network platform, doing that will only decrease the opinion people have of them.
I guess it can also be called natural selection ( or crypto selection) people that are too greedy will end up with nothing in the end, for example, people that were greedy and invested into bitconnect, they ended up with nothing, people that upvote their own comments same thing... In the end the strong survive and the weak perish, or so i hope
