> definitely a GPS-based user relationship table somewhere which reflects what you do to everyone they think has some connection to you I've seen this when I am sharing IP addresses with someone because we're both connected to the same WiFi. Especially if you block meta from being able to get any data about you but the other person doesn't. Meta then get data from that other person because it can't see anything from yourself. It helps when I'm looking for a gift for my partner - I can see what she's been looking at recently because its most of my adverts in Facebook.
