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.
Bit crypto does that by publicly recording all transactions on the Blockchain, this is kinda the same thing in that it’ll not just about being told ‘in total sixteen people agree’ and having to belive spez that he hasn’t just invented the number, it’s seeing who voted and how.
You can of course have more than one account and keep your identity private similar to crypto where your transactions are public but the owner of the walker can be private
