**Black pill trigger warning** This is true. Even worse is Fartbook assembles a shadow file even if you don't even have an account. Your stupid friends who invite you from their contact list (or let Fartbook have access to it) even go as far as to try and tag you on photos and shit. Gaggle and FinkedIn do the same shit even if you don't have an account. Forget about clicking the "do not track" as it has little to no effect on anything. In fact, don't use these "services" as they're all Three-Letter-Acronym Agency spy shit. A nice big database is forming on all your fun internet habits (including gaming and voice chats in and out of games) and other "bad actors" in companies like ADL (for example) will be coordinating with all of them - anyone can buy your data. Try not using Fartbook at all, ever and get one of those Nokia 3150 phones instead. Read The Gulag Archipelago for details on what comes next ... Imagine if the Bolsheviks had 10 years of Fartbook data to figure out who all the dissidents were?
