I don't have any links, sorry. I just remember this from the time I looked into using Adsense for my own AJAX site. From what I recall, Google doesn't care if you load and display one set of ads, but as soon as you start refreshing the adsense snippet (via an iframe, or removing the divs and recalling the snippet), Google brings the banhammer down quickly.
