RE: Flag-A-Whale: Deterring Junk Post Reward Manipulation!
I get where you're coming from and you've got my upvote for your effort, but the method you're suggesting here is like swimming against the stream.
It is the reward distribution formula that is causing the abuse on Steemit. You can't overcome abuse on Steemit without changing that formula first.
By the way, it's not only the whales that abuse the system. Minnows aren't that innocent either. Self-voting has an insane ROI for any level of investment.
The solution is to get rid of the reward pool altogether and let people tip the posts with their own money. They will choose which post to tip and how much.
I explained the details of this system in the post How to Solve the Reward Pool Abuse Problem Once and For All and we are discussing with other Steemians about the implications of such a system change at this moment. So, you're welcome to join the discussion.
