AdSense vs. protected pages

Do they get scanned?

I'd like to revisit this subject to see what the current thinking is.

If you put AdSense on password-protected pages (such as member-only forums), can AdSense scan these pages or does it use a more generic ad from the overall site?

Generic ads or PSAs. Go to the page without being logged in, and that is what the mediabot will see.

Furl displays targeted ads in password protected areas, how do they do it?
