Using your methods, can someone who is not registered on FB see anything or does one have to be a member?
Wget allows you to present credentials to a website, but it's a pain, as I recall. And it doesn't get you anywhere you couldn't get using a normal browser.
When I looked at his Facebook page, I was signed in with my Facebook lurker account, but it wouldn't let me see much of anything without being a 'friend'. I imagine they've either scrubbed anything interesting or moved it behind the 'friend' wall.
