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 see why this is an issue. I used Boost for Reddit, which let me see all my upvotes on my account by checking my profile. I always assumed this could be seen by anyone. Also, to respond to a comment lower down, this is not a democratic process, this is internet opinions. Voting in an election is NOT equal to agreeing with a publicly posted opinion. I know you voted, if you showed up to the voting booth on election day. But you don’t get to hide your identity either.
