Vote incentivisation for BPs used to be (or is still) rampant in Lisk
Definitely, and especially true for a lot of Lisk clones. That's one of the places which made me really think about what was happening.
I had a read through your post -- great stuff, something I had thought a bit about before as well. Curation reward used to be 50%, and I can't help but wonder if that was a better choice. I also miss a superlinear curve..
Something I'll have to dig into and think about more!
