What if rather than devoting time and energy playing whack-a-mole with every new instance that is spun up, a trusted group of people maintained and monitored a central list of allowed instances who have committed to a core set of values and show a good-faith effort to uphold those as much as their resources allow? The anti-Oliphant.
I have never been a large community moderator, so I imagine there are all kinds of flaws with this idea.
