Facebook knows who your friends are, even better than you do?
Last week, a Redditor named easyjet posted athreadon Reddit.
He mentioned that he signed up with an email address he never, ever used.
He even lied about all of his personal information.
ELI5: Just signed up for Facebook with a rarely used email address.
They know all of my friends immediately.

How does Facebook know who your friends are?
Did it scrape your phone for names and numbers?
Run a reverse-image search of your picture?
No Facebook doesnt attempt any sneaky or malicious ways to find our friend.
It uses a pretty complex academic field called .
That gives Facebook a basic idea of who you are, what your social circle is made of.
This information is sometimes better than your memory.
What FB does is not magic, its playing with permutations and combinations.
Nothing OP could have done about this.
Then, when OP finally created an account, Facebook had all those friendships ready to suggest.
