Neither @curatorhulk nor @freezepeach who have undertaken to mitigate flag abuse concerned themselves with financial rewards in the slightest. Their incentive was non-monetary. Society is far more valuable than it's economy, and disregarding that is less than optimal.
I dunno what happened to @curatorhulk, but @freezepeach is around. Instead of postulating their motives from nescience, just ask them why they do it. Curation rewards already exist, and no one is countering flags to receive them, nor have I ever heard of anyone doing so for that incentive. Far more valuable returns were their goal.
Fairness, opposing bullies, censorship, and idiots are all real reasons people have acted to oppose flags. Apparently, those are more valuable than curation rewards.
@curatorhulk is still around! I've gotten upvotes from them (and I'm not a target of flags).
That is good news. Last time I approached them about some friends that were being flagged I received no response from them.
I flag trash. You have received a flag.
