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.
Kbin and Lemmy are having huge federation issues at the moment, with stuff from Lemmy commonly having a multiple hour delay before showing on Kbin and sometimes it doesn’t show up at all. It might be a bug so we’ll see how it works when the next Lemmy version comes out.
Let’s be fair, lemmy instances are having the same issues federating, especially getting posts from the big instances. I presume it’s a server load thing.
