Since day 1, Steemit is always trying to solve the problem of abuse. I did get your point, and I had a point to make too. As you can see, I've given out close to $60 to people who provided good comments on this post. (who have not self--voted).
There is a group now working on a technical solution. However, there's an element to be social on a social network. Human behavior can be changed, if people see that you can actually make WAY MORE MONEY AND REPUTATION by doing good works that benefits many. Tech solutions have to work side by side with human behavioral solutions. Nothing is in a vacuum.
