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.

Yes, and that’s not the issue as I’ve been saying the entire time. The issue is that you have a right to know where it’s broadcast — both in the past and in the present. That’s what I’ve been saying the entire time. And the privacy policy needs to specify exactly what data is sent and where to. The privacy policy you cited did neither, it just stated that it was sent out.
