That was like the biggest thing i learned in computer class, that i already knew in 2002 or so. Later myspace became a thing, and everyone had a myspace name. Then facebook and some people used their real name. Then facebook asked you for your phone number, and i thought: well, that’s silly, who in their right mind would do that. Turns out the answer is everyone.

They even give them all phone numbers from all of their contacts linked to real name (even those who don’t have whatsapp)
What a database…
They exactly know who knows who and how connected people are. Nearly everywhere in Europe. Don’t know about US, I think there is more iMessage?
