How do I block a competitor ad that is showing on my adsense page (using referrals 2.0)? I tried to block some domains today using the "content domain Filter" feature this morning but they are still showing there (including my own domain as I run a PPA campaign for this same site on AdWords). When you choose publisher ads using Referrals 2.0 this do not means that only that specific publisher ad will be placed on that placement (the system select other PPA publishers if the one you selected is not available and this is my problem) Is there a missing feature called "Referral domain Filter"? Or I need to wait more for the "content domain Filter" take effect?
