Definitively a very useful feature if implemented.
As it is right know, I feel Steem as a ''value incubator''. With a option like this asterisc, we would be able to boost the 'organic writers' as you said.
PD: I'm using upvote bots for the same reason of everyone. But I believe that is the way to go long-term.
Regards :)
Unfortunately, I don't think something like this would be implemented. One has to hope though.
