Lemmy is one of the few ones platforms that attempts to preserve vote and mod action privacy, to prevent harassment, and encourage ppl to vote honestly. Several other platforms just let any user see who voted, which isn’t the best idea since it’s been shown that ppl are less likely to be honest if they know that their votes are public.
The main reason I added it for admins, is bc a lot of ppl have been understandably upset by downvote-stalkers, or those who downvote with multiple accounts.
Like anything, there’s the possibility for abuse, but at least by limiting it to admins only, we can prevent a lot of potential harassment that other platforms are currently allowing.
