Facebook to exclude phone numbers from reverse lookup - for users of two-factor authentication, anyway

A week or so back, we wrote to warn you about the privacy of your phone number on Facebook.

If you give Facebook your phone number, and mark it "visible to me only", then forward lookups are, as you would expect, blocked.

I can't go from your profile to your phone number.

That's a relief, since presumably you don't want just anyone who can find you on Facebook to be able to start pestering you directly by phone if you stop responding to them online.

But if I use Facebook's reverse lookup service (what is sometimes known pejoratively as a black pages directory), I can get your name from your phone number.

In other words, your phone number isn't "visible to you only." I just have to approach it from the other direction.
