There are 1.3 Million accounts on STEEM, which is a 3 year and 4 month old blockchain. So of course there has been many who have done whatever they could to gain profits by using multiple accounts with bots to do anything from circle-jerking content to mass-abuse the upvote bots (including me) in order to gain on their non-human content.
We do believe that among those accounts is only a few handful of people with extraordinary knowledge about STEEM and Engineering + some real life assholes ;)
