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.
Except it isn’t that bad, you have a literal example of it working which I doubt you have checked out or will check out, and you clearly don’t seem to mind telling people you are downvoting them anyway. There’s a very huge gap between what people will argue for just because it’s the way it has always been for them and the actual reality.
