Not sure if it's a bug or not, but I thought you took out all the ads with audio. I find them annoying, and am sure many others do too.
We don't allow our advertisers to use them, but there are thousands of ads on the site, so once in a while one slips through. If you can send details about which ad it was and which page you found it on, we can remove it. Thanks!
