I know what you are saying here, and it might sound right on the surface, but economically I am not sure it is the best play. Most of these guys have bought steem and continue to buy steem. If the goal is to create and keep a higher steem price (maybe it's not?) you want the people who are actually buying and holding steem to be earning the most. I am not sure what the right solution is here, but screaming proof of brain and giving the investors grief is probably not the best way to help steem go up in my opinion. Ideally we should want to do whatever is going to cause people to want to buy and power up more steem, providing a link between steem purchases and higher earnings, but this line of thinking likely does the opposite. Not to mention it really is a fine line between circle jerking and friends supporting friends which is normal social behavior. Beyond the most extreme examples like you mentioned, it gets harder and harder to distinguish between the two, which becomes a slippery slope rather quickly. Just me 2 centz :)
