About moderation: main thing to consider is that assume that if your group or ‘space/place’ isn’t moderated, any random person is going to be spamming it.

So start from there, as in who is moderating some space, and whether it needs moderation.

If Rostra group/subreddit is going to be used within a “circle of trust’ or ‘web of trust’, then moderation requirements are minimum. But if it accessible as read-only , or as read-write place for random trolls, then what kind of interactions are possible.
