How Does Facebooks People You May Know Algorithym Work?

Facebook's 'People you lot may know' is a phrase that seems harmless, if a bit formal - 'Oh come to this party! There'll be loads of people you may know there!' - but in the last few years it's go synonymous with that creepily accurate Suggested Friends carousel featuring people who yes, you do know simply, my god, how does Facebook KNOW you know them?! Is Mark Zuckerberg actually a sorcerer? Or more than pertinently, what is the basis for Facebook suggested friends? Is it stalking? Is it based on profile views? What exactly does information technology mean?

Facebook'south official line on this, on their help page, explains that they make selections for your Suggested Friends based on 'mutual friends, work and education information, networks you're part of, contacts you've imported and many other factors'. It's the 'other factors' that are the about interesting, considering how goddamn vague they are - especially when a suggested friend crops up, and you have no mutual friends in common.

Who is in my Facebook suggested friends and why?

But having a brief scan over my ain electric current suggested friends, there are at least three people there that I haven't met, I've never worked with, we didn't go to the aforementioned school, I have no mutual friends with and they're not in my contacts. One of them is someone I'k fairly certain, afterwards doing a quick search on other social media sites, is currently seeing my ex. Then why is she being suggested?! Is this to do with the 'other factors' Facebook mentions? I don't know her! Were we once in the same buffet? Has she, completely understandably, been stalking me? Have we finally found the definitive answer to how you can tell when people have looked at my profile?!

What is Facebook suggested friends algorithm - what is it based on?

Then many questions, then many conspiracy theories. Thankfully, I've done the hysterical researching, so when that guy you slept with who never whatsapped back and you can't stop thinking near pops upwardly on your suggested friends, you don't accept to.

Are your suggested friends based on your location?

In ane of the best cases of 'ER, NO I DIDN'T MEAN THAT, Shut It DOWN' Facebook revealed in 2016 that location data was one of the factors in suggested potential friends, before days later retracting it and saying they absolutely didn't. Cool.

There were a number of slightly worrying reports of how eerily authentic the supposed algorithm is; 'Seriously, I've had plenty reporters ask me, freaked out, why Facebook is recommending their protected sources' tweeted Violet Blue, a reporter on cybercrime.

If true, information technology likewise ways that Facebook uses like technology to the NSA.

During an investigation, Fusion constitute a load of anecdotal testify pointing towards location services being used. One example was a man who had attended an anonymous gathering for suicidal teenagers, and had then seen one of the teenagers he didn't accept any contact with other than being in the same place, popped upwards as a suggested friend. They approached Facebook who said: 'Location information past itself doesn't indicate that two people might be friends, that's why location is only ane of the factors nosotros use to suggest people yous may know.'

When Fusion had published an article, understandably, explaining how this is a privacy mess - Facebook immediately retracted it. The statement was changed to the fact that location services had been trialled a year before, only weren't one of the very vague 'other factors' described on the help site.

The journalist in question described 'repertorial whiplash - I've never had a spokesperson confirm and so retract a story so quickly.'

One way to stop any apps using your location is to change the location settings on your telephone, or get rid of the Facebook app and utilise it on skillful ole Safari. Other browsers are available.

Are your suggested friends based on who has looked at your profile?

There is no hard show that someone else's activity affects your page - and a Facebook employee was fairly clear on their stance in a recent Quora thread:

Thanks for your illuminating and rich response, Peter. Only I discover it difficult to believe that, when trying to create the perfect suggested friends list, Zuckerberg wouldn't have wanted algorithm boot into gear when you search for someone, or if someone searches for y'all. Considering that's the purest way information technology can tell if y'all want to be friends, surely? Plus, there are merely too many anecdotes to ignore.

'I recently viewed someone who I oasis't been in touch with for many years and who I didn't desire to be in bear upon with,' says one bearding user on Quora. 'Two weeks later I had a friend request from that person. I have no mutual friends and this person is far removed in my network of friends. Unless this person suddenly remembered me after almost twenty years since I have contacted them, and then I have no other caption.'

In a recent Vice investigation into how this suggested friend list happens, David Liben-Nowell, a computer scientific discipline professor at Carleton College who studies the structure and development of social networks said:

'My hunch is that [Facebook is] using names you've searched for or profiles you've viewed to advise friends to you. It would almost be dizzy for them not to: if y'all've shown an interest in a person while using Facebook, and so y'all've as proficient equally told Facebook that you might want to accept some kind of relationship with them.'

Agreed - it does make a whole lot of sense, if they're trying to make the friends they suggest as authentic every bit possible. And in that location's besides some fairly compelling evidence pointing to the fact that the friend grid works off the basis of who is looking at your profile, so why non suggested friends? I mean, that makes fifty-fifty more than sense, if y'all think about it.

Are your suggested friends based on your phone contacts?

This 1 is a definite yes. In one of the many app updates, you will have inadvertently synced all your phone contacts to Messenger. And if y'all've allowed Facebook to sync your phone contacts, then it'south going to suggest you connect to them online. It can exist freaky, though, if you don't realise you've put people in your contacts because y'all're drunk, then they get suggested back at you.

'Somehow my suggested friends listing is always chicks I take had one night stands with,' says a Reddit user who says words like 'chicks'. 'Facebook somehow looks through my contacts on my phone and uses their phone numbers to propose it. It's kinda creepy when you see a girl who you met one fourth dimension and didn't fifty-fifty know her terminal name, but somehow they are suggested for you lot.'

An easy way of getting rid of this via the Facebook app on your telephone - go to settings, and scroll downwards until y'all meet 'Sync Contacts'. Hit 'remove Facebook'. Done. Removed.

And check out the box that comes up as you lot're almost to remove the contacts:

'If you choose to remove your imported contacts, friend suggestions for you and your friends may become less relevant'. YEAH MATE. THAT'Southward SORT OF WHAT I Desire COS YOU'RE CREEPING ME THE F OUT.

Are Facebook friends suggestions based on other tertiary party apps similar Tinder?

The official line on this is no. In fact, information technology couldn't be any more than a 'no' if they tried, every bit they country on site: 'We practice not use cookies from third-party sites to generate or rank People Y'all May Know'. Well at that place you are then.

Nonetheless, if y'all're getting a scrap freaked out by the fact that Tinder matches/people you've Bumbled accept suddenly started cropping up, then you're not solitary - it's been a flake of a recent thing. And if yous don't have their number in your phone, and then how the hell do they know this if they AREN'T getting it through Tinder?

Well, it's likely that your Tinder friction match will have as well tried to stalk you on Facebook, although remember Facebook claim they don't advise friends who search your name.

But the other, less speculative, solution is that y'all accept their number on your Whatsapp contacts. Because Whatsapp bought Facebook, so if yous've been 'sapping, and you haven't un-synced your Facebook contacts (every bit above), so practise that immediately.

Exhausting, isn't it?

Tin you turn off or remove Facebook suggested friends?

Yeah - indirectly. If you block someone, and then they won't show upwards on your suggested friends listing. So if you take any especially triggering people from your past, then it might be worth taking a deep jiff, having a dram of whisky (or, similar, a glass of juice) and doing the deed.

Oh, and you know how you can specify people who y'all don't want to come up in that horrific On This Day characteristic? They won't come in your suggested friends either - which might be a good idea if you don't want to all-out block someone, yous just don't want them popping upwards all the time.

You're welcome.
