Is there a proposal or place to vote to show support for continued free downvotes?

I have been downvoting what I consider abuse of the Steem platform since long before we got them for free and so sacrificed some potential curation rewards. Things did improve when big accounts started downvoting. I can still find plenty of cases worth dealing with. Just look at who is buying votes from various bots and you will see people doing it for Actifit posts where they have not even added any description. This is just playing the system for profit whilst adding no value. There is also still plagiarism out there. If nobody does anything then it will get much worse.
