I have been looking at the behaviour of the Mediapartners Google bot - we need a snappier name, AdSenseBot? - and I've noticed it pulls some pages that dont contain any ads.
I've been very careful to make sure that AdSense is not on search results on my site, but AdSenseBot picked up 55 search pages yesterday (out of over 7000 displayed by my visitors).
There have also been some AdSenseBot hits on my other domains that have never contained any AdSense ads anywhere.
Is anyone else seeing this sort of thing? I figure it must be related to the clients hitting my sites in some way - perhaps related to the Toolbar or something? I am just nervous that Google will see their bot going to search pages and drop me!
