Mark Zuckerberg Denies Knowledge of Non-Consensual Shadow Profiles Facebook Has Been Building of Non-Users For Years
It has been widely reported that Facebook builds profile of people even if they have never signed up for its services. However, in a hearing with the House Energy & Commerce Committee on Wednesday, when New Mexico Representative Ben Lujan asked Facebook CEO Mark Zuckerberg if he was aware of the so-called practice of building "shadow profiles", Zuckerberg denied knowledge of it. Here's the exchange: Lujan: Facebook has detailed profiles on people who have never signed up for Facebook, yes or no?
Zuckerberg: Congressman, in general we collect data on people who have not signed up for Facebook for security purposes to prevent the kind of scraping you were just referring to [reverse searches based on public info like phone numbers].
Lujan: So these are called shadow profiles, is that what they've been referred to by some?
Zuckerberg: Congressman, I'm not, I'm not familiar with that.
Lujan: I'll refer to them as shadow profiles for today's hearing. On average, how many data points does Facebook have on each Facebook user?
Zuckerberg: I do not know off the top of my head.
Lujan: Do you know how many points of data Facebook has on the average non-Facebook user?
Zuckerberg: Congressman, I do not know off the top of my head but I can have our team get back to you afterward.
Lujan: It's been admitted by Facebook that you do collect data points on non-[Facebook users]. My question is, can someone who does not have a Facebook account opt out of Facebook's involuntary data collection?
Zuckerberg: Anyone can turn off and opt out of any data collection for ads, whether they use our services or not but in order to prevent people from scraping public information ... we need to know when someone is repeatedly trying to access our services.

He doesn't deny knowledge of it, he says they do! And he just doesn't have the data on hand. Sheesh, what a misleading title.
Everyone knows Shadow Profiles are real, that is how they know all the info they do when you sign up.
How is a non-user different from someone who is neither a user nor a non-user?
Any sufficiently unpopular but cohesive argument is indistinguishable from trolling.
"Congressman, in general we collect data on people who have not signed up for Facebook for security purposes to prevent the kind of scraping you were just referring to [reverse searches based on public info like phone numbers]. "
So, then, you're telling us that you're collecting the data to ensure nobody is collecting that data, is that correct?
If they have the MAC of any ethernet device that I own, then there is something seriously wrong with the public Internet that needs to be fixed immediately -- either that or everyone has out-and-out spyware on their computers and devices. Beyond your local network no one should have your MAC.
I don't understand why they left him off the hook so easily on this point. They could never collect consent from someone that didn't sign up for FB, so how is data collection could be legal?
Zuckerberg's nose is growing. Just sayin'
because his lips are moving, he is the biggest liar in washington right now
Politics is Treachery, Religion is Brainwashing
How is collecting data on non-users helpful in preventing reverse searches? It would seem to me that by not having that data non-users are best protected from searches?
Mod me down with all of your hatred and your journey towards the dark side will be complete!
then how can they opt out from getting their data collected?
i think facebook should be shut down, all their computer hardware confiscated and run through a shredder and the employees personal computers and other gadgets searched for other people's personal info and if any is found they should be investigated for identity theft
Politics is Treachery, Religion is Brainwashing
Lujan: I don't have a Facebook account. What does your shadow profile of me say?
Zuckerberg: Just a sec...it says you enjoy viewing Natalie Portman on Wikibellybutton.
Lujan: Wtf, I just jer...did that for the first time last night!
(-1: Post disagrees with my already-settled worldview) is not a valid mod option.
"Zuckerberg: Anyone can turn off and opt out of any data collection for ads, whether they use our services or not... " ...how, precisely do I turn off and opt out of FB data collection without signing up for FB?
I'm rather curious.

The apps running on your devices can access the MAC address and transmit the info over IP. Wireless access point know your MAC too, etc...
Everything I write is lies, read between the lines.
Ask Bill Gates that. 20 years ago called and wants its deposition tactics back.
It might happen with badly configured IPv6.
Among other, IPv6 addresses can be created by adding a suffix derived from you MAC address to the prefix advertised by your router.
Of course, there are privacy extensions, which generate addresses by adding random nonsensical suffices to the prefix, and a well configured IPv6 stack should generate several of those and prefer them over the MAC-derived one.
(i.e.: your laptop will respond when called by it's MAC-based IPv6 - useful for services, e.g.: SSH - but when contacting the web, it will present itself with a random addresses so your mac address should never be revealed in some webserver's logs).
Facebook supports IPv6.
A badly configured IPv6 combined with some clever javascripting (e.g.: the "like" button that you see on virtually any website when you don't have FSF's "Privacy Badger" activated) makes it possible for Facebook to track you by your mac address no matter which network you're connecting from.
(I'm saying facebook, but it works just as well with any other IPv6 support social website that has its buttons plastered all over the web: Twitter, etc.)
So, if you use IPv6, remember to enable the bloody privacy option on.

Until you sign up, you are an unwitting, unwilling user.
He's getting rather old, but he's a good mouse.
With all the hate suddenly piled up on the company, someone has to point out, that they've done nothing illegal. Not even unethical — certainly, not grossly so.
The information they keep about people was given to them voluntarily — either by users themselves, or by their friends and acquaintances. And what they now know, they are free to share — sell, give away, publicize, it is up to them.
Contrary to frequent assertions by the weaker-minded, there is no "right to be forgotten".
This whole "grilling" and questioning is quite extraordinary and barely constitutional, for it has most of the markings of a criminal prosecution without any crime.
That said, Zuckerberg does seem like a dork and an "accidental" billionaire, without the faculties, abilities, and guts normally necessary to achieve the power he wields.
In Soviet Washington the swamp drains you.
I believe the word should actually be "either", not "neither", and the answer, of course, is Heisenbergian uncertainty. The wave function does not collapse until observed. :-)
There are three groups: People who are known to be Facebook users, people who are known to not be Facebook users, and people who might be either one. In the first group, you know their account info, so you know who they are, and you know that they have Facebook accounts. In the second group, you know enough about them (name, phone number, address, whatever) to believe with a reasonable degree of certainty that they are not Facebook users. In the third group, you don't have enough information to decide either way.
That said, what the GP post appeared to mean was that there are active users, inactive users, and non-users. The GP erroneously conflated inactive users with non-users.

Zuckerberg took maximum advantage of the fact that the questions came from people mostly lacking the technical knowledge to judge his responses. For example, when asked if Facebook could track users across devices, he acted as though he didn't know. Is there anyone here who believes that? I wish we could ask him a few questions on Slashdot!
Zuckerberg also said that Facebook doesn't share user data, just uses it to predict which advertisements users are likely to respond to. In that case I'd really like to see what gets sent when someone uses Facebook to sign into a third party website.
I don't know what a shadow profile is, but collecting data on anonymous visitors to your website is not a privacy violation, it's practicing security.
I'm surprised that the comprehension around here seems to be about on par with the congresscritters.

No, no, you have that backwards. Facebook uses everyone. Everyone does not use Facebook.

There is such a thing as a shadow profile. It is a shame that Zuckerberg denies its existence.
I resisted to create a Facebook account, but five years ago I did it. Many people had sent me invitations, and it looks like that with the information other users provided, Facebook correctly guessed many things about me. It did not asked my my home town: it asked me to confirm their guess. Same for high school, university, occupation, place of work, etc.
I do not know if Facebook "knew" all this about me or was guessing based on data provided by other people. Facebook knew that a large portion of people that invited me had studied on a particular high school, and other worked for a particular company. Anyway, my "shadow profile" was alive and well when I first met him.
Too bad I am deleting my Facebook account in a couple of weeks.
They're not supposed to do that!
I guess that phrase pretty much sums up the reason for this Congress hearing's existence :)

Zuckerberg says he is not familiar with Section 230 (the law that protects ISPs from liability for third-party content.) That would be like the CEO of SmithKline saying he doesnt know anything about pharmaceutical testing rules.
If his lawyers after all this time never briefed him on Section 230, he is either lying, willfully ignorant, or being poorly served by his legal team.
Until you signed up, you're an unwitting, unwilling MERCHANDISE.
"Mr. Zuckerberg, you're full of shit. I didn't think it was possible for a (purported) person to have a higher bullshit content than Ajit Pai until I heard the drivel that came out of your mouth."
ELOI, ELOI, LAMA SABACHTHANI!?
Also you WAP is on your private network. Nothing outside of your private, logical subnet needs to know you MAC.
Not necessarily true. Many automated configuration algorithms use MAC addresses to ensure some level of uniqueness or as a tie breaker.
The most prominent use is automated IPv6 addressing. IEEE EUI-64 embeds your MAC within your IPV6 address if not statically or DHCP assigned. All someone needs to do is query the IPv6 address in a browser script to get the MAC address of most everyone who does not have a IPv6 DHCP complaint ISP.
Your first point is basically what they were banking on. Most of Congress lacks the technical expertise to verbally spar with him on most of these issues. He is employing the tactic every software engineer ever has when talking to non-tech executives. Plead ignorance to simple but damning questions and give overly complex answers to others such that management won't understand and doesn't want to look stupid. I really wish they would have pulled in some of his engineering leads that HAVE to be familiar with the product implementation so he couldn't plead ignorance so easily.
You second statement I think he was just abusing the double meaning. They aren't sharing data in the sense of a business deal where they get paid for the data, but they absolutely know they share a ton of information with developers and anyone plugging into the site to provide "enhancements" to their service.
They're not supposed to do that!
There's no network technology-based need for them to do that, but if the operating system makes the data available to them they can and some do use the MAC address as a unique device identifier. The major mobile device OSes have stopped providing it.
Note to ACs: I usually delete AC replies without reading them. If you want to talk to me, log in.
Lujan: It's been admitted by Facebook that you do collect data points on non-[Facebook users]. My question is, can someone who does not have a Facebook account opt out of Facebook's involuntary data collection?
Zuckerberg: Anyone can turn off and opt out of any data collection
HOW? How can someone, who isn't a facebook user, opt out of this data collection? If by "turn off" he means "not use the internet", that's not an answer. Zucktard.

No, no, you have that backwards. Facebook uses everyone. Everyone does not use Facebook.
The first time I used a script blocker, years ago, on any of the "popular" sites, and especially news sites, there were many facebook tracking scripts. You didn't find out just how many there were until you started tracing them back to see who ran them.
So I am completely certain that Facebook collected the Users names of those who logged into the sites, collected data about everything they read, almost certainly collected their real names, and distributed that data directly to..... who knows?
Oh....... wait......... we do know now exactly who they were selling or giving almost everyone's data to. And no doubt there are plenty of others.
Seriously, if that festering asshole in charge of running the worlds largest weaponized data collection center isn't aware of the fact that they collected and weaponized data against everyone, and people believe him - well I have some some oceanfront property to sell them in Colorado.

With data provided by users, Facebook knows a lot about non-users.

Somewhere back in the bowels of Slashdot, I made a report of my experience when I installed my first script blocker. Facebook had more trackers than Google. Google was easy to find. You just looked at the names of the scripts that were blocked, they had "google righ in them.
But I had to whois a lot of others, and by cracky, there was facebook with multiple trackers on all the pages of popular sites, especially on news sites.
So if the idiot doesn't know that he has people writing tracking scripts, maybe he needs to pay attention. But he knows.
Too bad I am deleting my Facebook account in a couple of weeks.
Happy sarcasm noted. block scripts too to make it more effective. I had to use facebook for some projects I'm working on. But as they finish up, I'll delete my account too.

People who are known to be Facebook users, people who are known to not be Facebook users, and people who might be either one.
Except for a handful of slave children in India, everyone is a Facebook user whether they want to be or not.
In Soviet Russia, no one uses facebook. The rest of the world-facebook uses you!
The Clinton example is an excellent one: As I recall, earlier in his testimony, it was established exactly what fell under the definition of "sex" for that discussion. If he said he did have sex with Lewinski, it actually would have been a lie, and most Americans would still be confused.
