Been bringing up this issue many times. We don't the Steemit behavior on other social sites. We don't see how many dislikes or amount of money that post made(since they don't have that feature).

So when someone creates a posts on other sites, it's to share information and communicate it to an audience. The popularity is what is focused on other sites. To gain popularity, we communicate with others in the community.

It is similar on Steemit but when you include the monetary system with a social media site, the behavior will change because we know that without a doubt that there will be those that lie, steal, and kill for monetary gain and also clouds judgment in decision making.
