Facebook uses location to suggest new friends

I'm not sure if it is either new or surprising.

I did an experiment some 3 years back from within a corporate network -- the difference being that it was done on a desktop, not mobile. The sequence of events was roughly:

- Spin off a new VM

- Create a brand new email address with fictitious identity

- Sign up to Facebook using the newly created fictitious identity

Result: The suggested "friends" were folks in that building (who were on the same network).

(The experiment was performed to demo how creepy such networks are.)

How awkward would it be when the FBI agents parked in the van outside your house keep popping up on your suggested friends list?

Genius. Let's write that screenplay!

I don't understand why people use the Facebook native app at all. Their mobile website works quite well and should avoid many of the issues with the app (location sharing, battery drain, etc).
[+] drcross|9 years ago|reply
Facebook recently disabled their messenger platform on the website, when you click the messages tab it brings you directly to the app store to install their app. This means you have to use the App to message people. The app requires such egregious permissions that I absolutely refuse to install it. It's a shame because it worked perfectly in the past.

Because it offers a far superior user experience...for the times I find myself in self-loathing after checking Facebook for the nth time, at least I want to not be struggling with the interface.

The thing with Facebook is that I use it when I know I want to give away information. For example, when I'm at an airport about to takeoff to an unfamiliar city but I'm not sure which of my casual friends (too casual to send out an email blast) are at the destination, I appreciate the location-based feature of Facebook that detects that you're at an airport and makes it easy to autofill origin and destination. I want my location to be known and so, I might as well use the native app.

I really thought this was already a well-established and known fact. I saw friend suggestions quite often after attending events where I ran into very loose acquaintances I never spoke to but share a few friends with. That by itself isn't too surprising, but the fact that this happens after we were geographically close led me to believe that this is common knowledge.

Goddamned Facebook!! Creating environments filled with unintended consequences everyday of the week.

There are so many untrained, misguided, semi-literate people in the world, who just get thrown into these environments totally unprepared. It literally sickens me.

Sorry I woke up today morning to read this - http://timesofindia.indiatimes.com/city/salem/21-yr-old-woma...

Parents get blamed. Police get blamed. Govts get blamed. Blame goes around. People get defensive rather than constructive. What a mess! Seriously how the fuck is anyone supposed to be prepared technically and socially to deal with this stuff?

[+] jasonkostempski|9 years ago|reply
That's a shitty story, but blaming Facebook for it seems a bit of a stretch. By that logic, photo editing software is responsible; computers; electricity, etc. A horrible society is definitley responsible for that one.

Linkedin does this too. It suggested that I connect with an academic copy editor. My only other connection? We sat next to each other at a co-working space. Of course Linkedin was not using geo-location. They must have noticed that we were both on the same network.
[+] Jdam|9 years ago|reply
agree, LinkedIn suggestions are really, really good/creepy, way more than Facebook, at least for me.
[+] cylinder|9 years ago|reply
I can't think of a single reason to use LinkedIn's native app.

> Facebook uses location to suggest new friends–which could be a privacy disaster

No, the privacy disaster happened when Facebook was allowed to collect all that data in the first place.

What if I moved out from a neighbourhood because I had enemies there, we didn't like each other? Now I'm coming back to my parents house and facebook reminds me about them and them about me?
[+] m0v_eax|9 years ago|reply
If you have actual enemies, it might make sense to block them on things like Facebook, LinkedIn, etc..
[+] gmarx|9 years ago|reply
Do you have enemies? Does a typical person have enemies?
[+] HBreakhh|9 years ago|reply
I don't expect anything to Facebook when it comes to privacy.
[+] braythwayt|9 years ago|reply
Well, there are several levels of non-privacy to expect:

  - Facebook collects data about me
  - Facebook shares my data with big corporations who want to sell me stuff
  - Facebook shares my data with my friends
  - Facebook shares my data with people who aren't my friends
For many people, this is a surprising escalation of their expectations. For some, it is outright dangerous.

Zuck: People just submitted it.

Zuck: They "trust me"

Zuck: Dumb fucks

just because you shrug it off, doesn't mean they are above the law.

Just yesterday somebody warned that Facebook does location-based friends suggestion (was suggested to friend a taxi driver) and promptly accused to be tin foil hatter.

That's just how it goes every time.

[+] jedberg|9 years ago|reply
They probably aren't using location but IP block. In fact, I'm almost certain your IP block is used for both suggested friends and your Newsfeed.

I used to see my coworkers all the time in my Newsfeed, but now that I don't work there (and therefore we don't share an IP anymore) I suddenly started seeing them a lot less.

I go to their page and see they are posting, and after interacting with a few posts they started showing up again, but I have to go to their page and interact every few weeks to get them to keep showing up.

Also, whenever I go and visit the old office, if I use Facebook there, all of a sudden I get them all showing up in my Newsfeed again.

"Location information by itself doesn’t indicate that two people might be friends" - interesting, and guessing it was IP based so they might put more weight behind it, but I keep getting this for an ex-housemate. Nothing else in common, no common friends, just the fact we were both regularly in the same place/same network.
[+] xuhu|9 years ago|reply
The man from the article attended a common event with the other man who appeared on his friends suggestion list. Maybe facebook has a rule that if the event is small, the attendees can be assumed to have met IRL.
[+] m0v_eax|9 years ago|reply
I love it. I've wished this feature implemented for quite some time.
[+] zeeshanm|9 years ago|reply
They also suggest friends based on who has viewed your profile.
[+] pmlnr|9 years ago|reply
Or it may result in real-world friendships.

Too bad I don't have the Facebook app installed any more.

i never use facebook on mobile devices, i have a different "supervised" profile on Chrome for facebook use and nothing else.

i use it because of how many people are on there, but i wont let them snoop on me

[+] 0xmohit|9 years ago|reply
Do you need anybody else to snoop upon you if you're using Chrome?

Has Google stopped identifying a given Chrome installation using unique IDs?
