The possibility for authors/dapps to set a) max accepted rewards to author AND b) max accepted rewards to curator ---- both values required or set to default. Usecase: dapp wants to limit rewards for posts through it to 1$ for authors but to $10 for curators.

50% of the reward goes to curators = 10$, out of the remaining 10$ for the author 9$ goes to @null, and 1$ goes to the author.

This should be implemented for the entire Hive universe.

Otherwise other significant changes are needed, such as ending the use all together of curation bots, which is used by those exploiting the blockchain, including some witnesses, so their actions of using dozens and sometimes hundreds of accounts are not able to be automated in a way that blends them in with other actual users.
