Posts with 50 flags or higher need their payout reversed completely and account flagged down to negative 4 to 6.
IMO, this would be too easy to abuse. Bad actors could easily get 50 accounts to attack others with. Even if you made some threshold of rep of SP, its easy to imagine someone gaming the system.
I agree. This was just a suggestion but I think it can be implemented in some manner. If not into the blockchain but perhaps at the UI level. Hopefully, there will be a system in place.
