Community for moderation accountability?

This is inspired by this advice from a few months ago:

Stop giving shitty mods a free pass. Honest mistakes happen; but if the mod in question is assumptive, disingenuous, trigger-happy, or eager to enable certain shitty types of user, spread the word about their comm being poorly moderated. And don’t interact directly with the comm. I think that at least here in the Fediverse we should demand higher standards from our mods.

(Emphasis mine.)

In the past I have used places like [email protected] or [email protected] to call out mods on other subs, with mid-to-almost-high degrees of success, but I wonder if it would be better to have a dedicated sublemmy?

Here are my thoughts on what would make this effective:

• probably shouldn’t be hosted on .world due to the breadth of possible conflicts of interest with admins
• probably shouldn’t be hosted on .ml due to federation hurdles
• mods of the community shouldn’t moderate any other communities of any significant size, in order to make the whole “accountability” thing work
• mods should be willing and able to deal with substantial quantities of garbage posts because there would be a lot of “why won’t c/xyz let me be transphobic/say slurs 😡😡” type submissions which, left unaddressed, would outflood genuine criticism

This is still in conceptual form so I am interested what others think :)
