No, personally identifiable information isn't public information. What's exposed here is still personal information that you decided to make public, but presumably with the users consent.

On Facebook, there are granular privacy settings to control who can search for you by email/phone number if you choose to use them. They're accessed by going to facebook.com/settings (dropdown arrow @ top right), then "Privacy", then "Who can look me up?" ...the analogy would be opting to have an unlisted phone number in the white pages back when they were printed on paper and arrived on your front doorstep.

It can be, for a plurality of reasons. Phone books, court records, etc.
