@bitcoinflood, what you are suggesting needs to exist on a code level, and it becomes extremely complicated problem of coding the ability to classify something as a bot and still be decentralized. thats part of the difficulty in everything, how can you create an environment, that is neutral by code?

Until then, you can only do as much as abiding by the original mission statement of steemit, which is to curate the best content, and create the best content you can.
