Facebook – How ‘People You May Know’ Works Without Email Address

facebook

I created a Facebook account, and the email address was freshly created with that account.

I have never sent any email from that email address and the only emails I have received has been welcoming ones from Google and Facebook .

I go to the Facebook homepage, and it says "People you may know".

It lists two people one of whom I know. Where is it pulling them from? / What are the sources that Facebook pulls these things from?

Best Answer

Facebook may have suggested:

  • People you searched for earlier (even not logged in, but from the same machine!)
  • People who have searched for you
  • People from same school, workplace or village
  • People who have your associated phone numbers in their address book
  • Friends of people you have blocked
