Locking: rule 5, already answered, and no more to be said
Commenting from alt/backup account as Lemmy currently doesn't support posting or commenting as a regular user while a mod. Until there's a "appear as mod" checkbox when posting or something I intend to perform mod actions from this account. I've heard others have used this as a workaround successfully. My app of choice doesn't show reports as yet anyway so I'm already periodically checking in browser.
This technically violates rule #5 but I feel like it's a valuable information and discussion to have available.
