Not sure if you guys all have the same info, but I emailed YPN about ad blocking and received the following response. We're sorry to hear that you're having problems with our Ad Blocking feature. If you've allowed at least 48 hours after including URLs in the Ad Blocking feature, and you're still getting those blocked ads on your site, you may wish to either include or exclude the "www." part of the URL in question within the Ad Blocking feature. For example, if you're trying to block ads from www.abc.com, you may wish to revise the blocked ad URL to abc.com instead. Similarly, if you've entered in xyz.com as a blocked URL, you may wish to change that URL to www.xyz.com. Making these changes should allow our system to reset the ad blocking feature
