Every measure i can think of has some negative side effect that goes up exponentially as you increase the degree of that measure.
Curation - less $ for authors, assuming honest voting
Free downvotes - toxicity, bullying, possible collusion at high levels
Coverging Linear - punishes smaller votes
The idea is to use as little of these measures as possible while still being sufficient to bring about honest voting behavior from most stakers.
If you can think of other measures that can bring about this change we desperately need with fewer negative side effects, I'm definitely open to them.
