Steemit really needs to consider the reward and upvote system. They should implement the Gini-Simpson Index . The more you upvote the same account over and over the less percentaje of your vote is worth. In case of haejin his vote will be worth 11% and rancho 3%, it could be applied to the accounts you vote instead of your general voting power, that way we can curve excessive self vote and excessive bot buying, people would consider more about using the same voting bot without the bot being afraid of losing % power. I upvote myself and friends all the time and my index is still over 97% because i also upvote others. http://steemreports.com/outgoing-votes-diversity/gini-simpson/?account=ranchorelaxo&days=14
