Very interesting idea. I think as it stands right now that Steemit is still going to leave things in the hands of the people to control and direct so downvoting is our only option for the time being. However I do think they will need to address these issues as Steemit grows or it will just implode on itself and self destruct into a common Porn and filth site along with every other scam and sin out there. There is a fine line and we as users need to address, report and downvote anything that doesn't fit in within the Steemit community. If people would come together on this more we could keep the Steemit community more in control by the users and not by Steemit.
