Policing of any content is not a good idea, minnows are unaware of the platform and in some case may purchase the votes, additionally they are unaware of the kind of content that people like on Steemit, on one had steemit is promoting itself as lotteries on posts with $$$$ everywhere to bring in users but the reality is how do we discover new and good content, understanding the platform its issues and now flagging, we are decentralized so let it remain that way, why are some people trying to form the core and create it a central entity. The universe grew unchecked and its marvelous, i hope this example helps some.
