    I wonder from where they get the data if I don’t have Facebook or Instagram. WhatsApp is a shitty app that I begrudgingly use because of the parents groups and some relatives that I didn’t manage to make switch to signal.

      WhatsApp links you to a social circle and Meta has all of the information of said social circle.

      I don’t need to know you like soccer if I know 10 people who have a soccer team and you’re on all of their contact lists.

      Facebook absolutely builds ghost profiles for people who don’t have a Facebook profile. You see all of those “Like” buttons on non-Facebook websites? Those are cookies that are essentially tracking you. They may not have your first/last name or other personal data as a regular profile, but they can build a pretty damn good composite of you.
