I see no reason that increasing curation rewards in any way changes the extant dynamic for profiteers. It just increases the value to them of upvotes. Increasing curation rewards will be adapted to by bots to encourage hassle free profiteering via delegation.

The actual solution is to remove the ability of stake to profiteer from their votes. I have repeatedly pointed out one mechanism that can do that, the Huey Long algorithm.

I am confident that better minds than mine, such as your own, can devise others. After the EIP fork fails, do give it nominal consideration, please.
