I use uBlock Origin but Whitelist OzBargain to help support the site, however I have my limits of what I'm willing to tolerate and Autoplay is one such thing that crosses the line.
I don't know if this is a deliberate site action or one that "slipped through the cracks".
What I don't appreciate is doing my own thing on another website with OzBargain open in another tab and then suddenly I hear The Good Guys jingle.
Here is the code I pulled out of Google Chrome > Inspect Element to help isolate which ad it was: http://pastebin.com/taTEi0DE

You can opt out of Ozbargain ads. There is a dropdown in your profile.
