The url should point to the Gizmodo article; not the sensationalizing tweet. https://gizmodo.com/facebook-is-giving-advertisers-access-to... The actual story is FB enriching your profile with shadow contact information about you when you or third parties provide it with details it wasn't aware about yet. For instance when a friend of yours has your landline number in their address book and gives FB access to the latt…

Is this any surprise? Just a few hours ago the Acton article on the front page[0] talked about them doing this in WhatsApp: > Later he learned that elsewhere in Facebook, there were “plans and technologies to blend data.” Specifically, Facebook could use the 128-bit string of numbers assigned to each phone as a kind of bridge between accounts. The other method was phone-number matching, or pinpointing Facebook accoun…

Wasn't one of the conditions to get the deal approved by EU regulators to NOT share any data between services? [0] Did they just restart it because they found reprieve or simply decided to ignore the regulation?

Edit. Also this [1]. Does GDPR suddenly open the door for sharing this data "legitimately"?

Another personal observation. I have an Instagram account that I thought was fully incognito. I never connected it to any other social account, I used a separate email for authentication etc. Just days after the Instagram founders left Facebook I started receiving friend suggestion on my IG that were very very relevant. Those were people I knew in real life and mostly connected via Facebook but not only. I shouldn't…

Definitely location tracking of some sort. IP, location data from the browser (if allowed), and scraping photo metadata can all lead to them associating people.

This should have been obvious for anyone who is paying attention. When data collection and advertising companies such as Facebook (and Google) push a feature actually beneficial to users so aggressively – such as 2FA – during the sign-up process; you'd have to be naive to think it's for your benefit. It's not 2007 any more... tech savvy users should know better than to trust such organisations with any scrap of addit…

Tech savvy or not, really there's no way any current fb user would be concerned with it nowdays and they will continue to rat you out to the fb apparatus. You know how they say "ignorance is a bliss".

Hopefully? Hopefully this means we will see facebook employees faceing criminal charges!

If it's a corporate decision they won't be liable. "Similarly, individual employees, managers, and directors are liable for their own malfeasance or lawbreaking while acting on behalf of the corporation, but are not generally liable for the corporation's actions." from https://en.wikipedia.org/wiki/Corporate_personhood#Case_law_... I don't think GDPR has any tooth in this.

Maybe not. But you can hope about the future. Laws are created because of malfeasance. And they can change.

The reason I never give fb my mobile is if you use a pseudonym account, it will suggest your profile as a friend to anyone who has your mobile in their phone contact list (eg ex-partners, stalkers, employers, drug dealers). Found that one out the hard way. I know Zuck wants me to preemptively upload my nudes, but still.

This is basically how FBI Director Comey's secret Instagram account (and thus Twitter account) was unmasked. But it was even worse - you are suggested to 3rd party people who just follow the people who know you: https://gizmodo.com/this-is-almost-certainly-james-comey-s-t...

Yep, something similar I discovered recently that if you sign up to Instagram with somebody's email that they use on Facebook then within a day or two you'll start to see all of their friends from Facebook whom are also on Instagram in your recommended follows. All of this happens without email verification..

i'll be ok-ish with a $5B fine or whatever makes sense. it'll be cheaper then to hold the employees liable.
