Thank you so much for being receptive to my ideas of economic reform. I had always been inquiring about whether a superlinear curve with a linear tail was possible and the n^2/(n/c+1) you've posited seems to do the trick very well.

Not to be too pedantic but

The specific curve it behaves like can be derived by calculating the limit at infinity. In the case of this curve, it behaves like the curve f(n) = 10n

If you were referring to your example of n^2 / (n/5 + 1), did you mean f(n) = 5n? As that's where I believe it converges

Now as an alternative, is it possible to simply apply a x% 'spam tax' up until a certain point then allow it to receive full rewards beyond that point? So for example, anything under 1 Steem is taxed at 50%.

Assuming we increase curation to 50% and that indeed becomes the dominant form of staking rewards, it would mean micro votes are earning no more than mean curation and they're probably at least as well off doing something that actually adds value.

A solution such as a tax avoids overly punishing genuine interactions at low levels of rewards such as organic comments while still providing a very clear disincentive for profit based micro vote farming.

Of course overall I'm quite receptive to this curve and think it's pretty neat. I'd like to hear your views
