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’m sure that someone will dox themselves, then somewhere else mention where they work. Post on some gonewild pages (is that a thing here) and then make a poorly worded opinion on a sensitive subject and lose their job. Of course Internet hygiene is important and you shouldn’t dox yourself but after several years you’ll slip up and these things will bite you .
Doesn’t have to be major slip ups. Just little tidbits over time on a comment here, a post there, and the aggregation of that data can really narrow the results down.
Truth.
