Can someone please explain how they are doing this?
Friends, family, and even people you briefly meet, rat you out. Often without them even knowing by sharing their list of phone contacts.
And what happens when you change your phone number? Does that become a new shadow profile? What of they change your name in their contact list? I'm trying to gauge how Facebook handles the inconsistencies of navigating contacts who don't have Facebook accounts
We can only guess. But they can probably detect contacts for which the phone number is updated or which have several assigned phone numbers.
Also all Android / iOS apps with Facebook and Google trackers in them share device info and data easy to correlate, icw sites having FB pixels also.
They do more than just the phone number and name. https://www.howtogeek.com/768652/what-are-facebook-shadow-profiles-and-should-you-be-worried/
It talks about the use of photos, people mentioning you in a post, etc. Sure, facetook publicly said they would be backing off of visual recognition, but how much do you really trust that company to do jack-diddly if there is potential profit? Anyway. If you change your phone number, but the same group of people still have you in a 'field of contacts,' their tools can almost certainly fit those puzzle pieces together. Same if you change the phone number. Identifying people is easy if you have metadata.
This is starting to look like a major problem. Are there any tips on how to solve this issue?
