Thanks for letting me know. Couldn't find the Downy one, but I just got an audio one on the homepage for some dishwasher detergent and grabbed a screenshot of it. I just sent it off along with info about the Downy one to our ad networks so hopefully they can track that bullshit down quickly.
I noticed that after the audio ads finish playing, they switch to a completely different ad in an attempt to hide their origin.
If any of you can tell me where on the homepage you saw the Downy ad (top of the page, sidescraper ad, or one of the 300x250 box ads on the left) that might help too.
