>>Go down the list, how many of the affected site have there advertisements labeled as such?
Most ad providers don't allow you to do that. I believe Adsense in particular prohibits it. It's a violation. So basically almost NO site will do that, at least not for all their ads. Not just the ones that were hit by Panda.
Regarding blending, it's the same thing. Adsense basically tells you that you have to blend their ads into the content. So almost all Adsense sites do that.
In fact many of the winners do the things you listed.
Both of those are near the top of the winners list and do both of the things you mentioned.
