Is my instance de-federated if this community is “completely empty”?

Just out of curiosity, how would one do this (in general terms)?

I hope I never have to because I’m sure I would not figure it out lol

idk if this could be subjective, but what do you mean by upstream here? Does that mean it’s included in most distros?

It’s a shame, they’re like twice as expensive as canned tuna for some reason where I am!
