These papers weren't using Adsense. Is it considered a TOS violation to have an ad with no content on the page? (Can't image what the bot would find, although sometimes it seems to choose ads based on other site pages when it's not sure what to display.)
Maybe it's time for Firefox Fridays where we all block our non-commerical sites to Internet Explorer users every Friday!
