Average total payout of the last 30 days.
For example if all minnows make around $10 total payout average per post in 30 days then a downvote could be adjusted to 10 cent. So it would take 100 downvotes to kill the entire total payout of that post reflecting that the community disagrees with it.
Of course such posts don't get much visibility so I would raise the downvote amount to 30 cent (per flag).
Thanks for making that detail clear.
I think it somewhat limits the harm that flags can do, but in my way of thinking, there should be no harm.
Flags should probably not exist.
