I guess it's pretty hard for every newbie to resist the temptation of self-voting since there's "free money" at stake, albeit it's only just 0.01. Greed like any other human emotion is something innate and natural. Steemit will eventually turn into a giant prisoner's dilemma where the people who abuse the system will gain at the expense of those who follow the "rules." (If there are rules to begin with)

Unless there's a way to penalize abusers through a downvote button, Steemit will become a free-for-all where everyone tries to grab all the upvotes. Then again, in the whitepaper, Steemit is a proponent for a no censorship social media. I wonder if there will be true value creation on Steemit...
