Yep, what you're describing is what I believe is called "Shadow Profiles", and they've been unapologetically doing it for years. Very likely, even if you have all the privacy extensions and jsblockers installed on your computer, or even if you go full RMS and only wget once a day to get your daily content and email, odds are Facebook has a full profile on you because of the people in your life who leak the information about you. Your folks filling out a form on Facebook saying that they have X children, your friends sharing their contact list with LinkedIn/Google/Facebook and you're on it, your workplace profile being crawled, and so on. Unless you go full on hermit, there's really no way to not be part of Facebook either actively as a user or passively as a shadow profile. Exfiltrating this data, or even so much as seeing the entirety of it also appears to not be possible to see what bits of your information have been gathered, to know who has access to it, to know what it's being used for, or even to deny them the ability to make profit on this information. It's incredibly frustrating, as if any individual citizen were to do this sort of reconnaissance and data gathering on another citizen, it'd be called stalking, and people would have legal means to redress. But the fact that even those who have not agreed to the Facebook TOS are still profiled and sold and used for profit without the aforementioned persons' consent seems very wrong.
