Something similar happened to me on Facebook. There was someone I was meeting in real life but we had absolutely no FB connections. No mutual friends. And I didn't even know she was on Facebook. Suddenly I saw her on my 'Suggested friends' list. The only reasonable explanation is that she found me on Facebook and viewed my profile. Facebook saved the incident and suggested her to me as a friend. Facebook forgets noth…

Most likely she looked you up on Facebook.

When you look someone up, there's a significant chance that you will appear in their "suggested friends".

My husband told me that his customers show up as suggested friends on Facebook. We always thought it had something to do with Whatsapp and Facebook. Now I guess it's just because he uses the Facebook app on his work phone. Crazy stuff!

At this point Facebook has enough data and capability to tell you not just who you're dating right now but who you're likely to date in the future, based on preferences and who you're likely to meet. They may not be doing it yet but I'd assume it's at least been considered by them.

> Despite having all GPS related features of Facebook and its messenger disabled, the Facebook Messenger app tries to access my GPS location at seemingly random times. This is troubling, and goes against the Play Store's terms and conditions for app developers. I suppose Facebook gets a pass on it through some unspoken agreement with Google, though.

do you really think that is possible ?

No that's not happening, it's just conspiracy nonsense.

It literally comes down to advertising/tracking. Because tinder is ad-supported for the free app, they're sending data directly to advertising networks (of which Facebook is one), and that's being used to track you. Per…

Most phones are android though and there you have to give up your contact list or simply not install the app.

I wouldn't be so sure. I noticed for the first time just a few days ago my phone's contacts were showing up on Facebook as suggested friends. These weren't facebook profiles, just a name, phone number and the option to email them. I checked all my settings for facebook and messenger apps and all 'sync contacts' options were disabled and I have never enabled them. I'm on android. So, my guess is they were somehow granted permissions on installing the app and then the options to disable this actually don't do anything. If there was an option upon install to deny access to phone contacts I definitely would have denied it - if they don't provide the option to do this on install, they're being sneaky.

I'm getting tired of how aggressive Facebook is at suggesting new friends.

Facebook sends me phone notifications telling me they've found someone I might know. I get it if it was a new profile and they want the ball rolling, but I have over 900 friends on Facebook already, many I can barely remember where I've met. Why do I need more people I barely know?

What is it that makes Facebook think their app is more engaging if my friend list if full of people I barely know and never interact with?

Agreed that they do not forget a damn thing. However, some users have their friends list hidden - so you could be having mutual friends with that person without FB telling you.

Why don't you just delete the Facebook app from your smartphone? That way, Facebook won't have access to your contact list. Therefore, this should not happen. I'm a casual Facebook user since like 2008, but I never even considered installing any of the Facebook apps on my phone.

This is irrelevant. You will still be tied to a unique identifier and tracked all over the web because your browser fingerprint (yes, it's probably unique: test here https://panopticlick.eff.org/ ) will be reported back for every site affiliated with an advertising network affiliated with Facebook.

Why do you keep posting the same thing over and over again?
