Even in chainbb you have the Post Rewards Beneficiaries system.
Authors that are in the featured posts made by those trails could be added to the system and it would give them the percentage they deserve. That is not that hard to do.
Maybe steemit could have something like that too.
That can be done. It's not exclusive to chainbb. Why it's not being done seems to be a mystery.
Whales should flag them to annihilation :-)
