How Facebook Outs Sex Workers (gizmodo.com)

An anonymous reader shares a Gizmodo report: Leila has two identities, but Facebook is only supposed to know about one of them. Leila is a sex worker. She goes to great lengths to keep separate identities for ordinary life and for sex work, to avoid stigma, arrest, professional blowback, or clients who might be stalkers (or worse). Her "real identity" -- the public one, who lives in California, uses an academic email address, and posts about politics -- joined Facebook in 2011. Her sex-work identity is not on the social network at all; for it, she uses a different email address, a different phone number, and a different name. Yet earlier this year, looking at Facebook's "People You May Know" recommendations, Leila (a name I'm using in place of either of the names she uses) was shocked to see some of her regular sex-work clients. Despite the fact that she'd only given Facebook information from her vanilla identity, the company had somehow discerned her real-world connection to these people -- and, even more horrifyingly, her account was potentially being presented to them as a friend suggestion too, outing her regular identity to them. Because Facebook insists on concealing the methods and data it uses to link one user to another, Leila is not able to find out how the network exposed her or take steps to prevent it from happening again. "We're living in an age where you can weaponize personal information against people"Kashmir Hill, the reporter who wrote the above story, a few weeks ago shared another similar incident.

  1. Their app reads your contacts... by emil · · Score: 5, Informative

    ...and this is how it knows who you associate with. In later versions of Android (and perhaps in iOS), you can deny permissions to read your contacts, but the app will likely work hard to get around that.

    If you have contacts on your phone that you don't want Facebook to know about, then you must not load their app

    - only access them through a dedicated, privacy-focused web browser (or an equivalent sandboxing app).

    I like FaceSlim on F-Droid. I would never, ever run their app. That thing is a monster.

      Wrong. I have two accounts. One which I've used for years on my personal laptop, and a second one I recently created behind a VPN and which I've only used from a separate laptop, within a private Chrome tab, with no personal details at all. There is absolutely no link between the two accounts, other than my own eyes looking at both. No pics, no FB app, nothing.

      Two weeks after I created the new account, FB started suggesting friends from my old account. I'm not sure how they do it but it's truly terrifying.

      All you need to do is visit one site in common with both laptops and they can link the two accounts.

    That's not a fix anymore. They have managed to build profiles on almost anyone. How do they know your bank account information if you don't have a FB account? How do they know it if you do and have never used your bank account with it? This has gone beyond scary.

    Simpler fix - don't be a prostitute.

    Prostitutes are more moral than clergy.

    Facebook connected me with someone I had brief contact with from back in the late 1980â(TM)s and FIDO BBSâ(TM)s. Predating my time on the Internet, this was puzzling to me.

    It turned out I contacted them once via hotmail and that was it.

    Yet somehow Facebook has this information, and to this day continually lists them in the âoepeople you may knowâ section.

    Close. The real problem is carrying a cell phone with the Facebook app on it, signed in with your account, while doing things you don't want Facebook knowing about. All they have to do is correlate the GPS locations from multiple devices to detect that two people are repeatedly in the same location at the same time.

    Your missing the point, even if you have never created a facebook account one exists for you they created. Thus if someone uploaded a picture of you to facebook and tagged your name in it, then they can tag your name on every picture uploaded to them with you in, even if they don't automatically tag those pictures they sure as hell know who you are and your name and relationships at a minimum. At this point there are probably very few people in the world that haven't had a picture of them uploaded and tagged.

  14. Facebook tracks your MAC addresses as well... by denzacar · · Score: 3, Informative

    Probably snoops your browser history and tracks to which cell towers your phone connects to as well.

    A while back, son of a distant cousin (distant in relation, close geographically) had some issues with his PC so he called me for help.
    It sounded like the issue was power related but he assured me that his PSU had enough power to run it all.
    It was the PSU. He read the wrong numbers on the box.

    BUT... After I downloaded a GPU test to check my suspicions about his computer, which naturally required an internet connection, and he took his computer home with an advice what to buy so his games would no longer crash the system - he starts appearing as "people you may know" on my Facebook profile.
    Despite the fact that we have no direct connection on Facebook. His dad is not on any social network. Same for his mom.
    And he's too young to be in social circles of our mutual cousins.
    But once his computer connected to the internet through my router... there he is.

    On another note... got a new phone which (naturally) has cell tower broadcast notifications turned on by default.
    Which I notice only as it starts pinging me with notifications as I go around town and move between different cell towers.
    Coincidentally, during that same walk I notice a former colleague on the other side of the street, going home from work.
    He doesn't even notice me, he's on the other side of the street, there's traffic between us, and I'm not about to shout and wave or jump around for him to notice me.
    We never were that close anyway... which is the reason why I don't have him in my Facebook contacts.
    But we do both have some of the same former colleagues in our friend lists... and I was just in his neighborhood.

    And there he is the next day on top of the "people you may know" list. He was probably on it the whole time... but now he's on top of it.
    As soon as his phone and my phone were near the same cell tower at the same time and as my phone connected to my wireless router once back home.

    Facebook has shadow profiles on everyone already.
    All it needs is for some of the gathered data to start matching to geographical and time coordinates one's technology, friends or even interests leave all over the place - and it can start making some pretty educated guesses.

    And there you have swallowed the "Big Lie" whole. The thing is that almost no sex worker is ever "trafficked". That is just a story vomited out by the anti-sex-work propaganda. No matter how often repeated, it is simply not true. It does however fit nicely into the deranged fantasies of many religious fundamentalists. The most extreme perversion committed by the police here is that they do charge sex-workers with having trafficked themselves. They also charge drivers (usually in the employ of an escort, i.e. a subordinate) with trafficking and just plain people that have helped sex-workers in anything remotely connected to their work.

    Sure, very rarely somebody is forced via threat of violence into sex work, but the thing is that usually the first or second client is the one to call the police on this, because customers of sex-workers are not complete scum.
