Sort:  

Why not both down vote and flag? I think it would be good to partially separate them out, where a down vote affects payout but not visibility or rep, and flag does everything it does now.

Perhaps put this in a post, open the discussion, and give feedback to the devs?

Really this would be a major upgrade, but it would also help separate payout from flagging where I notice where even non-negative accounts at 1-10 routinely disappear from Steemit.
