If it's not running on a separate server, then you can't eliminate just by blocking doubleclick.com or adsrv.com or some other such domain that hosts advertising. If it was hosted by the same server that produces the content, then it would be harder though not impossible to block. It would also be harder to just mass block like you can at the moment. You would need to block for individual sites by targeting the div class name that they use.
