I do get your point and this is something I thought about. The reason I don't think this would be an issue is because whales are already not voting on plankton or minnows. The situation only has the potential to get better on that front.

And nobody on the platform even pays attention to curation rewards until they have several thousand SP so the bulk of the curation for that class will still be among that class and the class directly above/below.

Now why would a whale or curation group currently upvote a plankton/minnow? It would be on merit/quality, nobody is now or would under this new system upvote this class for profit. There is no profit to be made there, it would be on the actual quality of their work. That's why I think this would be better. Get some rest :) Thanks for commenting.
