I think they either:

Or most likely both. Creepy stuff indeed.
- edf13 7y agoYep - all of above.... 690 App/Sites for me! Not overly surprising really
- StavrosK 7y agoI use uBlock Origin and Privacy Badger on my desktop and phone, as well as Blokada, and yet Facebook still had a bunch of app activity even though I never ever sign in to stuff using FB (or even gave the apps my email or any other piece of personal data). I literally just opened the app, granted no permissions, used it a bit, and Facebook associated it with my account. What the fuck.
- the_snooze 7y agoThey could be associating you server-side using persistent identifiers on your phone. For example, if an app has the Facebook SDK, it could send your IMEI to Facebook. Then, if you have a first-party Facebook app like Messenger, that too can send your IMEI to Facebook and link it back to your Facebook account.
