Edit: obligatory explanation (thanks mods for squaring me away)…
What you see via the UI isn’t “all that exists”. Unlike Reddit, where everything is a black box, there are a lot more eyeballs who can see “under the hood”. Any instance admin, proper or rogue, gets a ton of information that users won’t normally see. The attached example demonstrates that while users will only see upvote/downvote tallies, admins can see who actually performed those actions.
Edit: To clarify, not just YOUR instance admin gets this info. This is ANY instance admin across the Fediverse.
Self removals are hard to sync between instances, so a message you posted and deleted can linger forever.
For example, a message I posted from sopuli.xyz to a pawb.social post and then deleted shows as being deleted on sopuli, but is still visible on pawb.
Mod removals are all publicly listed neatly right here on the mod-log: https://lemmy.world/modlog?page=1&actionType=ModRemoveComment
Both links appear valid to me
Not the post, but the comment. Lemmy doesn’t scroll down when you link to a comment for some reason.
