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.
So when Threads decides to federate, they can slurp all this information.
That would be massively concerning and that should be blocked. Ideally votes should remain only on the current instance. Anything shared with other instances should be anonymised. This would need to be re-architected imho.
People come here to get away from Reddit now that trust has gone. Trust and a feeling of safety is vitally important to continue to build this platform.
