I can see your point and understand the bid voting should no longer be an option. The algorithm improvements will make a big difference in discouraging this behavior.
What is your opinion about "promoting" on specific terminal like ESteem and Partiko. Not buying votes, just promoting content buttons on those portals?
I like see sponsored content on esteem. I think the best way is to burn steem for promotion. Creates bullish demand for steem while reducing the supply, an absolute home run of a combo.
