You should only ban a user for activity outside your "turf" in extreme cases, that endanger your users; at most that endanger your community. Clearly not the case here.
Also, a year long ban? Seriously??? The only situation that I can see a mod/admin doing it is when they want to permaban a user, but still say "ackshyually le user wasn't permabanned lol. we banned them for a limited time lmao."

I can see a (good faith) admin as wanting to do a 1 year ban instead of permanent in hopes that in a year a person will reflect on their actions and have a different outlook when it expires. Though yeah in this case it's probably just to make people not go as far as they could in calling it out, so they can say "it's not that bad, it's a temporary ban".
Even if they [a hypothetical admin, not this case] expect the person to reflect on their actions, a whole year seems too long. Odds are that the user will simply forget about the comm/instance and move on.
Yeah that is true, at least it is for all the ones which aren't critical-mass communities or instances (ones that are a large percentage or engagement and userbase here). The ones that are, would likely be more detrimental and someone banned from those would be more likely to leave Lemmy, or violate the will of admins by evading those bans on new accounts.
