My point is I don't think curators primarily curate for rewards. Because the rewards are much lower than the work involved. At best, the rewards are a bonus for whatever primary reason that curators vote for posts. As a clear example of this, people vote for posts all the time on social media sites such as reddit, without any expectation of a financial reward.

But nonetheless, the suggestion I've seen so far that seems mostly like to improve curation quality is to change reward window/payment algorithm, which would result in more rewards being paid to manual curators vs auto-vote bots under the current status quo.
