early adopters of Steemit were able to make big rewards.. I saw old posts from 2016 where some people would be rewarded $50 for a simple comment.. and $1000 posts were so common.. nowadays with the increasing amount of user the pie is getting shared among more and more newbies wanting their shares.. the whales are very upset because of the increasing mining difficult.. technically speaking we are mining steem using our brain.. but every-time new steem are created the difficulty keeps increasing.. just imagine the time when one could mine hundreds of bitcoin with that dual core cpu in one day compared with now.. So the so called policing is to chase as many people as possible into not sharing the new steem which are created everyday.. I believe there is a fixed limit to the number of currency that can be created in one day. I know a few whales who self-vote in comments like "wow" and "nice" and gets $10 but these people are so greedy they won't let a minnow earn $1
