What is a 'top curator' in this scenario? Is it the person who uses most of their voting power/percentage (excluding on themselves)? Is it the person who upvotes posts with a combined highest rewards payout? I hope neither by the way.
That is a good question to ask. According to the current system it would be the person who upvotes posts with the highest combined payouts at the earliest stage.
I think you're right. This would most likely mean many bot votes for known authors who always earn a lot, so it wouldn't promote a system where new people (or anyone besides the lucky few on Trending) could thrive.
