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 anyone surprised at this: welcome to the fediverse, please treat everyhing you do or say as public.

    The way to achieve privacy around here is by following the long forgotten arts of the old internet before Facebook was a thing: use a Nick name and don't tell strangers on the internet your real identity.

    Your home instance will act as a proxy and only they have access to your email and IP address. That does stay private.

    So, as long as you trust your home instance to not leak or disclose your connection or sign up data (which would be illegal in EU countries), just sign up with an alias.

    A very positive aspects of this is that it should allow us to detect voting manipulation by correlating the activity of certain potentially malicious actors. If Lemmy instances take vote manipulation seriously and do their best to block bots this has the chance to make Lemmy / Kbin much more transparent and credible than Reddit ever was.

      I whole heartedly agree with this perspective.

      Additionally, and this is an unpopular opinion, but trying to maintain a Nick or online identity over many years is folly. You end up with a huge repository of personal information, increasing the risk that it can be connected to you personally.

        This has come up as part of those requests to migrate accounts between instances. “I want a persona that stays with me for years”… Is that actually a good idea though!?

      No, an alias will only give you pseudo-anonymity. Even trivial analysis like counting which words occur together frequently in your writings can reveal with very good accuracy any other alt of you, so the available information of you is basically everything you have shared online with enough accompanying self-written text.

      Your home instance will act as a proxy and only they have access to your email and IP address.

      Your home image typically doesn’t proxy image loading, those are hotlinked to the Lemmy server that the image was uploaded to. So your IP address and browser string are going to other Lemmy servers.

        The posts just contain a URL which doesn’t include the uploader’s ip address or their browser string.

          When the browser loads that URL, hotlinked image, that server has to have your IP address to return the results. Just browsing posts those images are being loaded.

    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!

      I think your comment clearly illustrates what might go wrong with it. If they need this data for sorting or something else absolutely, then I would be happy if they just hashed the usernames/instances or used some other form of UID.

      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.

      I’m almost willing to bet that big tech companies are already doing this. They got the motive and the means. No doubt Meta or Google have dedicated some of their servers to mining our Lemmy data in this way.

        With only around 100k users and most people using anonymous usernames that cannot be connected to their identity it would hardly be worth the effort, time or money.

          You’re looking at this from the wrong point of view. The fediverse is not just lemmy: Threads, Tumblr, even BlueSky (albeit with their own protocol, but anyone could just modify their fediverse enabled app to convert their data to be applicable to BlueSky’s protocol) are quickly setting the stage for a new norm. The more websites integrate the fediverse into their stack, the more data outside the immediate sphere of influence of these major corporations can be harvested. To what ends they’ll use it, I don’t know – but I don’t trust them with it.

      They will know the user but not the person in real life. Even if you know that my user is more conservative on some points or more liberal on others, how can you use that for nefarious action ? Unless you know where I live and who I am, the data is useless.

      People need to be aware that sharing your personal information on the internet is never a good idea.

        It’s very difficult to both A) have meaningful conversations in a public space, and B) conceal your identity from a dedicated adversary. Once a person has a long post history, it’s likely that an observer could narrow down their identity to a very small group, if not a single person. Every post you make reveals something.

        Even if you don’t ever explicitly state it, your age range and gender can likely be guessed with high probability by your writing style and/or little tidbits of info you leak without thinking about it. Same for political leanings. You might casually mention the brand of car you drive, or your favorite foods, or just reference something you experienced as a child that is not universal. All of these things leak information, and while each one seems insignificant, in aggregate they can tell a detailed story. Just knowing that you’re a Canadian who speaks both French and English eliminates about 99.8% of the world’s population as possibilities.

        Back on Reddit I used to create fresh accounts all the time, but then I’d go and join the same subs, post with the same writing style, and generally express the same worldview. If anybody cared, had a good grasp of statistics, bothered to collect the data, and put in a stupid amount of time to it, they could likely match all of my accounts together. I was never too worried about this because…well I just didn’t care. But I did have a cyberstalker at one point and it made me think.

        I wouldn’t be shocked if someone could match me to one or more of my Reddit accounts just from this one comment, tbh. I’m leaking information here like a sieve! Not many people have the skills to do that, and the few who do are unlikely to give a rat’s ass about me. HOWEVER, as AI becomes more advanced, anyone with computer literacy will be able to do analysis in minutes that might currently take an expert days or weeks.

    I downvoted the beans and I don’t care who knows about it. I’d do it again.

    This is useful to know though, thanks. I guess assume everything is public short of your password (unless your admin is particularly nefarious and has altered the code to store passwords in plaintext for some reason).

    Good find, albeit a bit horrifying.

    I wonder what the GDPR implications of this is. As far as I understand, even free, privately run services are required to abide by GDPR and offer data insight and deletion. They’re also required to state clearly what happens to user data.

    Edit: Apparently people have varying takes and feelings on what the GDPR does and does not say, so I urge you to please read the summary of GDPR data privacy here: https://gdpr.eu/data-privacy/ as well as the summary of what constitutes personal data here: https://gdpr.eu/eu-gdpr-personal-data/ It’s easier to have a good and fruitful discussion if we talk about what the GDPR actually says.

    Reading these comments, seeing so many excuses, sarcastic responses, and handwaving, makes me realize a great deal of users really need to develop some imagination.

    This is not about privacy. It’s about data that can easily be used for targeting and profiling users, and how that creates countless avenues for targeted harassment and wide scale retaliation. It’s about all of the innumerable ways public vote information can and will be abused to manipulate scoring across the site with targeted/automated shadow banning and shared blocklists. Raise your hand if you trust every single admin to never abuse such a tool to curate the outward appearance of an instance to fit a narrative.

    For a different example: I could say something about how great Nazis are right now, and have a bot programmed to read every single person that downvoted me, add those names to a shared blocklist, and viola, I’ve made myself and all my alts invisible to the people that would challenge me on a massive scale.

    I promise you this is going to be a big issue as tools for this site get more sophisticated over time.

    Couldn’t we just use a hash for the usernames instead?

    Nothing too over the top, but just a simple hash and match that instead?

    Also, there’s way too much trust in instances. Like, one person could easily make a post on lemmy.world, go on their personal instance, and just give themselves, say, 2000 upvotes.

    Instances should have their own settings on what instances are allowed to keep a local copy. (Default behavior should be to get the post itself from the instance “hosting” it).

      If that is a solution you’d need to change the ActivityPub specification. You are more than welcome to submit your idea.

      Also, there’s way too much trust in instances. Like, one person could easily make a post on lemmy.world, go on their personal instance, and just give themselves, say, 2000 upvotes.

      I’d first have to create 2000 users, then I’d have to send 2000 upvotes. And then I’d get blocked by all instances.

      Instances should have their own settings on what instances are allowed to keep a local copy.

      This is also not compatible with the ActivityPub spec but even if it were you’d win nothing because as soon as you fetch the post it is still on the server.

    How often are we going to see this postage? I think this is the third time I’ve seen it at least
