Also, it seems to me that @utopian-io is only upvoting the winning hunt. Do you mind explaining this further?

So, Utopian's amazing AI will check all the Steemhunt's posts that are upvoted by @steemhunt, and analyse if they are related to the area of science, innovation, tech or open source, @utopian-io will upvote the post with a 5% relative voting power.

But it seems to me that there are many more that would fall into these categories.
