What about moderator activity as a way to “mod the mods”, if you will (if that could even be done)? Some subreddits had a laundry list of mods that did nothing, even ignoring calls for new, active mods.
Like complete x% of mod activity to remain a mod for that sub, possibly have that % vary by sub size and/or number of mods for that sub.
Edit: what’s the appropriate shorthand nomenclature for magazines? Mags? ‘Zines? Will get out of the “subreddit” habit eventually!
