That's a very good observation, now I see how some accounts move the reputation ladder quicker than others. I guess it's a side effect of allowing bots in the system. When you put some rules in place, people will work around them and 'bend' to perfectly fit the system. Steemit is an example, laws in countries are the same - a law of unintended consequences (or intended but not officially broadcasted). Anyway, Steemit, despite some inefficiencies, is still a very good tool and being the first of it's kind I can forget some issues. Also, this is only BETA version right now, isn't it?
