Yes, I agree completely.

One possibility I have envisioned is to cause high SP votes in relation to the current post payout to be shared more with the curators than the author. That is if a high SP (botvote) hits an article with a current payout of .50 and has a vote of 25.00, then based on a logarithmic scale, up to 50% would go to the curators, not just 25%

This does not take any large blockchain reviews and is nothing more than simple math. It makes using bots unprofitable. It would not affect normal vote flow and rewards and also highly encourages larger whales to seek out unnoticed work.
