I noticed this a few months ago while working on some 'hidden'
pages.  Google's bot would show up within 30 minutes or so and fetch
the page.  I was concerned that the 'hidden' pages would be indexed
although from what I know about Google's methods that seemed unlikey.
I asked Google about this and they replied that the adbot is fetching
pages only to determine content for Opera adwords and that the pages
are not considered for the index.

I've found Opera's adwords to be very helpful.  If an approriate
ad is displayed for one of my pages I've done something right.
