I have been reading trough the discussion. And I think we can tackle one problem at the time. Number one is bots that upvote content while being paid for. It can be a massive disturbance of the economy within in the blockchain. This can be solved by simply having real guidelines for what an usefull bot is. Such as @Cheetahbot where other bots that are just simply put there to earn steam by being paid to upvote are considered a disturbance. This may require some changes in end user policy.
