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 think there are some problems about voting being public. I don’t think this is one of them.
I don’t mind people blocking me, and if I don’t appreciate the type of content people provide I’ll block them liberally. It’s not necessarily anything personal, I’m just cirating my experience.
Furthermore, I strive to be on instances where nazi sympathisers would be banned, and where instances tolerating them would be defederated. The only issue is identifying and weeding out troll accounts.
You wouldn’t know that your instance is infested with tankies and fascists. You can’t see their posts because you’re on the block list.
