Automation is good for a business. Most of the people aim to delegate the work to others to enjoy and take a rest.
That's why most investors who powered up, see it good to autoupvote others to have that passive income without doing much work, just like in the real world where directors of companies hire workers to do the main work and just to control them sometimes. But we are all in another world. The crypto world !
Most of us want to see the decentralization here. Everyone has his/her own definition about what it is and how it should be. The best one I read in a comment :
.... decentralization means people can come together to define the set of rules of behavior instead of one entity doing it...
and
It’s in progress
That's what 
If we just complain about things we don't like without doing anything to change them, everything will stay as it is !
That's why I wish the automation will stop in the proof of brain tribe. I think it's unfair to see someone doing his best to share good ideas and useful information and being unseen. While some are autoupvoted and placed in the trending page right away, no matter what they write. Is that a decentralization we all want ?
I curate a lot in the new page and I see how things are done. It's hard to not see that when you care about the platform. If you consider this the best platform, and you want it to grow, so maybe it's time to make some changes ?
It's not even about fairness. But about the reputation of the platform. When people join here and see the same authors trading again and again with any content they write, they understand that's not about the content, but about something else. It's not always the case with everyone in trending, but still we see some repeated names, just because of being autoupvoted by the right guys.
I was autoupvoting as well, but I stopped that. I do mostly a manual curation, and it seems not that easy to do. It consumes a lot of time. But I chose to be in proof of brain, but not proof of something else. I chose to grow this way.
Maybe I'm wrong and autoupvoting is ok, I don't really know. It's the same about self upvote, some consider that ok, some are against that at all. It's hard to satisfy everyone. Maybe each has the right to do it his/her way, but we still have to have standards to follow.
