Facebook is under a lot if heat because they actively try to encourage the user to enter PII and even have policies such as no aliases and all accounts should belong to one person. Can't remember if I even needed a phone nr confirmation or if that was Microsoft. The sole purpose of a Facebook account is to be a one to one mapping to a person, and everything posted or visited is obviously tied to such an account.

Not like hacker news where you don't even need an email address to sign up, creating a throwaway account if you want to post something private takes one minute. Good luck with that on Facebook.
