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.
To illustrate op’s point I’m going to spin up an instance, federate with everyone, and not tell anyone what that instance is.
Then I’m going to feed all that data into my new website, called Open Lemmy Stats, where anyone can query the user data ive accumulated. The homepage will be ripe with insights, leaderboards and all kinds of data on prolific users.
Additionally, I’ll display a snapshot/profile of a random user by feeding that users data to GPT4 to make inferences about the user’s political affiliations and display the results.
Worst of all, I’m not going to out my instance for everyone to know it as the one to defederate. In fact I’m spinning up a few instances that will host innocuous communities that I plan to mod and support to give my instances cover for their true purpose: redundant fediverse datastreams for my site, Open Lemmy Stats.
I’ll also have a store where anyone can buy my collected fediverse data for a handsome sum.
Just kidding I’m not doing any of this. But someone absolutely will or already is.
You know, I came in here with the mindset that the topic of discussion here isn’t a bad thing; I’m largely pro information-should-be-open-and-available. But you’ve argued a very solid point, and I’ve changed my mind on the issue. I appreciate you sharing this perspective!
Honestly, why not? The data is already being recorded. At least this way it’s public and the rest of us get to interact with it. It might even scare a few people into paying attention to the information that they disclose about themselves and increase their digital hygiene.
