Your question is really unrelated to this.

You could instead ask, why is no one selling votes anymore? They could easily sell their votes for some extra returns, right? Or instead of selling just ask the people they gonna upvote to give them a small percentage in beneficiaries, right?

Why was the EIP introduced with 25% downvote mana? Why did vote selling stop as a majority to exist right after that? Who tried their best to disincentivize vote selling to make curation as fair and trending as unique and deserving of the rewards based on the content and who was behind it rather than who was buying votes or bribing curators?

I didn't stop my attempts back then to improve curation and proof of brain, even when I had South Korean stakeholders with 50m+ SP who were equally as much against downvotes stop me and I sure won't stop now from someone who has one of the worst reputations on Hive pulling this scheme in exchange for higher returns and an unfair growth compared to the rest of the platform. It's surprising it even lasted this long, guess people are just busy with their own things. And I will try my best to keep proof of brain and curation for the sake of content after the next hardfork that'll make curation curve linear again.

I've repeated myself enough now for a week and won't be discussing this matter further, at least not against the same hivemind and same arguments over and over.
