Steemit is open source for everyone. There is no set rules. We each use our account as we see fit. Which includes self policing. You will find some who don't like the idea of upvote for upvote and others that do and some that are indifferent to it. Its the same as the bot wars that are currently going on. Some are against bot use and others are not and lots are stuck in the middle.
Thanks for your comment !
