I think we would need to see a specific proposal on the parameters of the curve. If it is too superlinear beyond the low end then I agree.

yeah it definitely depends strongly on where the main curve lays. If we penalize especially small votes (< 1$ or < 0.1$) but have it almost linear at everything above that might be a good way to avoid bot farming while keeping the rest the same for the vast majority of users. On the other hand if the main curve is around 10-50$ it would be more on the shoulders of the smaller users and lead to more bid bot farming.
