I’ve been noticing this more and more in the modlogs, with it proven via the “creator” option in some instances’ modlogs that the people doing the bans were mods and not admins, and when I first joined Lemmy, one of the things that were held as a universal truth was that this absolutely could not happen.
I would say yes, it’s allowed simply because it’s only possible using whatever commands one can access through the API. So the functionality is there, it’s just not easily accessed by the default interface. Same with being able to see who voted how on every post (Tesseract has this function) because it’s still tracked, just not a thing on the default interface.
Try Boost or Voyager, I guess? I only know what I’ve seen sporadically in conversations about it here on Lemmy and I don’t use either of these apps myself.
They added it to the default interface. At least for admins, not sure about mods.
Admins have full control over the entire instance. Of course they get mod options in communities they aren’t necessarily mods of on their instance.
