I think Hive is fairly organic for now, but then it's too small to attract many who are after attention. We also know that cliques will support each other and get to trending every time. There are so few of those that it's obvious what is happening. It will get interesting when we get to millions of users and maybe get big in certain areas. Then the scammers will take notice, but it will not be so easy to manipulate in terms of rewards without spending a lot.
I don't take too much notice of so-called influencers on any platform. It's quality of content that matters. I may make more on Hive than some wanna-be influencers :)
