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.
Excuse my ignorance, still super new to Lemmy. What’s kbin?
Kbin is another open source link aggregation program with a different developer that uses the same protocol as Lemmy (ActivityPub), so kbin and Lemmy instances can communicate with each other. If you see anyone with “@kbin.social” after their name then that’s where they’re from. You can check it out yourself here as well kbin.social
