This was always a risk, exactly like Justin, with ill gotten gains to be cancelled, on steem it was understood that consensus is king, on hive it was expressed as the very first principle, consensus is king. I would be happy to see what you base your idea on that shaming them is effective when they show no shame by their flagging. There's no fighting abuse to hide behind, it's simply relentless punishment.
It serves for them to control the pool by driving people away, which is something that ought to be punished. If you leverage your stake to punish, others should effortlessly be allowed to punish you, shaming would be nice, if it had any chance of being heard, but I bet they'll hear power down and gtfo much more clearly and since that's their entire thesis it'll be that much more deserving. This was always the issue, without a way to deal with bad faith actors swiftly they brain drain trying to "reach" them, at least if some whale that cared about this could begin an effective end to it with such a tool. It's long past time to do something about it, scrap RC, make transactions cost steem, nullify stake and every % over that effectively diminish the power down potential and burn the difference with no max cap making it into another prisoners dilemma where the consensus can form to banish you or make you into an impotent thorn.
