Don't even need that. Meta crosses multiple platforms now - Instagram, FB, WhatsApp, etc. All you need is for someone you know to have you in their contacts list, and the hit the "allow access" a single time. All of that data is then scraped, cataloged, and cross referenced with everyone else. Name, address, phone numbers, birthday, work address - anything your contact felt it convenient to add about you in their phone. From there it's just a matter of time until data mining of second and third level contact - or outright data leaks - fill in the rest of your profile and demographic information.
