I can go to instagram and take a picture of my foot and get 3 likes. Kim Kardashian could post the same picture of my foot on her instagram and get 3 Million likes... it's never going to be fair when there are so many different things that go into the equation, everyone has different followers, everyone markets their page differently (sharing to other social sites to get more attention etc), it's impossible for the rewards to scale by post quality because it's a pretty subjective thing.
