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.
Nothing private in fediverse except when you are selfhosting yourself.
and not interacting with anyone else.
If post views are public that’s a fairly poor implementation on the developers part. I’m sure it will change over time.
E.g. someone using your account to view illegal content in a community you are not a member of, and you being held accountable.
It’s not possible to make votes private is your care about no manipulation happening. Otherwise any self hosted instance could just communicate any made up amount of votes.
Cant they? Sure, they would have to make up new users instead of simply saying a number, but what is actually preventing that?
We can monitor actual active users that an instance has. Anything artificial in volumes enough to have an impact would be noticeable in some way to other instances.
Given the number of lurkers on Reddit, you would probably end up with a lot of false flags.
Can’t someone talk ActivityPub directly and do this? If the instance is responsible to authenticate the users, the instance can just directly talk ActivityPub to the rest of the network and tell it users and votes on the fly, without even Lemmy running there.
