I was surfing on digg.com when I cam across this gem of an advert. Its for some pornographic/adult content but seeing something like this on the google adwords network certainly came across as a surprise.
Its the first time I came across something like this, I always thought that google would have some filters to stop content like this from getting through. I am really not sure if google has started allowing links for adult content on sites like digg. But someone would have some explaining to do at least in this matter.
