"We cannot eliminate such behavior entirely, but we can make it less economically viable."

I think that we can indeed almost completely eliminate such behaviour, with appropriate incentives, and do far more than merely reduce it's impact. While some folks will do irrational things (as do I, by not delegating to bidbots) few rational people intent on prudent finance will act contrary to their financial interests. I hope I'm not irrational, but merely more highly value other metrics than financial.

Tweaking the rate at which profiteering extracts rewards intended to promote curation can tweak that behaviour at best. We can eliminate incentive to do so altogether, and we should.

Thanks!
