I don't know... your suggestion would still benefit the people who have lots of money + many followers, right?
I mean yes it sounds like a better (until proven wrong) solution compared to bots but I think the whole problem is way bigger: The powerful decide.
I appreciate all suggestions but I think Steem isn't rewritten to take power from the rich and give it to the poor... like Steemit Hood :D
Well, it shouldn't be. There's nothing wrong with people having money. And of course people who have more money will have an easier time with... pretty much everything in life. It's the nature of money.
But this would give an alternative to people wanting to advertise their work but not wanting to use the vote bots.
It'd be a risk, but advertising in the real world is always a risk: you spend money on advertising without a complete guarantee of returns.
That's just business.
