Facebook profiles.....?

[kaire]

You cannot view Facebook profiles without having a profile. If you see that person is leaving Wall posts, they have a profile. If that person's name is in black and their profile pic is a question mark, it means they have changed their privacy Search settings so that only their friends can see them. No one will be able to search for them, which ultimately means that no one can add them -- only they add people. Perhaps Meg has changed her settings to that. In that case, you will have to ask her to add you.

It doesn't mean they deleted their account (if someone deactivates their account then everything will be gone, even photos).
