Authorized Fetch (also referred to as Secure Mode in Mastodon) was recently circumvented by a stupidly easy solution: just sign your fetch requests with some other domain name.

    It’s the unfortunate reality. Social networks simply cannot in offer privacy. If they were upfront about it, then people could make rational decisions about what they share.

    But instead they (including Mastodon) pretend like they can offer privacy, when they in fact cannot, resulting in people sharing things that they would not otherwise share.

      It’s not as black and white as you make it. The options aren’t “perfect security” and “no security”.

      The option that most people that experience regular harassment want is “enough security to minimise the shit we have to deal with to a level that is manageable even if it’s imperfect”

        While you’re theoretically right, we’ve seen in practice that nobody really offers even the imperfect privacy you describe, and on decentralized systems it only becomes harder to solve.

        A Facebook style centralized network where you explicitly grant access to every single person who can see your content - is as close as we can get. But nobody is trying to make that kind of social network anymore, because there isn’t much demand for it.

        If you want a soapbox (Twitter/mastodon/bluesky, Reddit/Lemmy/kbin, Instagram/pixelfed, YouTube/toktok/peertube) then privacy is going to be a dream, especially if decentralized.

          Vulnerable folk are looking for community, not a soap box. The goal is to connect with other folk whilst being as free as possible from harassment.

          It’s absolutely possible to achieve that without perfect privacy controls.

            Privacy and being free of (in-context) harassment aren’t the same thing. Your posts can all be public but your client can filter out any harassment, for example.

            If the goal is privacy so that people who aren’t in the community don’t know that you’re in the community, and don’t know what the community is even talking about, I’m skeptical that it’s practical. Especially for a decentralized network, I think that the sacrifices needed to make this happen would make the social network unappealing to users. For example, you’d need to make it invite only and restrict who can invite, or turn off any kind of discovery so that you can’t find people who aren’t already in your circle. At that point you might as well just use a group chat.

              Privacy and being free of (in-context) harassment aren’t the same thing.

              They’re related. Often, the ability to limit your audience is about making it non trivial for harassers to access your content rather than impossible.

              If the goal is privacy so that people who aren’t in the community don’t know that you’re in the community

              That’s not the goal. The goal is to make a community that lets vulnerable folk communicate whilst keeping the harassment to a manageable level and making the sensitive content non trivial to access for random trolls and harassers.

              It’s not about stopping dedicated individuals, because they can’t be stopped in this sort of environment for all the reasons you point out. It’s about minimising harassment from the random drive by bigots

                Hmmm I think I understand the intent. I’ll have to think on it some more.

                My gut tells me that protecting people from drive-by bigotry is antithetical to content/community discovery. And what is a social network without the ability to find new communities to join or new content to see?

                Perhaps something like reddit where they can raise the bar for commenting/posting until you’ve built up karma within the community? That’s not a privacy thing though.

                What would this look like to you, and how does it relate to privacy? I’ve got my own biases that affect how I’m looking at the problem, so I’d be interested in getting another perspective.

                  You’re thinking about this in an all or nothing way. A community in which everyone and everything they post is open to everyone isn’t safe.

                  A community in which no one can find members or content unless they’re already connected to that community stagnates and dies.

                  A community where some content and some people are public and where some content and some people are locked down is what we need, and though it’s imperfect, things like authorised fetch brings us closer to that, and that’s the niche that future security improvements on the Fediverse need to address.

                  No one is looking for perfect, at least not in this space.

                    I don’t think I’m looking for perfect, I’m looking for “good enough” and while authorized fetch is better than nothing, it’s nowhere near “good enough” to be calling anything “private”.

                    I’m thinking that maybe we need to reevaluate or reconsider what it looks like to protect people from harassment, in the context of social media. Compare that to how we’re currently using half-functional privacy tools to accomplish it.

      Decentralised, open social networks cannot offer privacy. Private groups are perfectly feasible within a locked-down system with the necessary gatekeeping.

      In theory isolated Mastodon servers without open signups could work as their own private communities as well.

      All you need to do is take out or several restrict federation capabilities, and most of the Fediverse privacy problems go out of the window.

      I think someone built a social network on top of Matrix that could use the builtin E2EE to restrict read access. Like with normal social media, you would need to hack servers or clients to get any chance at reading those posts unnoticed as an outsider.

      In this case, Threads (and Tumblr, Foursquare, Mastodon) can mitigate this problem by simply not federating with anyone but known-good servers.

        It’s about the nature of the network. If it’s just a little bubble where you only see and interact with your friends, it’s probably doable. But nobody seems to want that anymore.

        People want soapboxes like Twitter or Reddit or tiktok or YouTube. Privacy there is a lot more complicated and dubious.

        In this case specifically, I think that the bad servers are spoofing as good servers. Which seems solvable (else cryptography signing things wouldn’t work), but still.
