Many people done that. Most of the people are doing this for the money. I do not blame them. The problem is the bad marketing of Steemit. Steemit is marketed with the money earning opportunity. If the people would be more active (use the platform in a natural way), regardless of the price of Steem, then maybe that would be better for the whole blockchain. Millions are using Facebook, Twitter, Instagram, etc., and they cannot expect even a single cent from those websites. The Steem blockchain has two huge advantages over these websites.
For example the freedom of speech (absolutely no censorship), preserving information. Everything you post to the Steem blockchain will remain there as long as the Steem blockchain exists.
