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.
I don’t think that’s a non-issue. If you host an instance an can see everything on it, that’s one thing, but if everyone with an instance can see these things from all other instances, that’s a different story. That way literally everyone can see all your up and downvotes. That’s not the end of the world but that’s definitely an issue imo. I can already see people getting canceled not because of an old tweet but because they upvoted something controversial years ago lol.
I’m constantly upvoting/downvoting things on accident on mobile. Something I’d like these mobile apps to implement, is the ability to disable voting so I can avoid this. I’m mainly a lurker having vote history available is a little concerning to me.
