Really?
I had this e-mail from Google today:
Hello,
Thank you for participating in the AdSense Referrals programme. We will be retiring the AdSense Referrals programme during the last week of August. After that time, AdSense Referrals code will no longer display ads.
If you currently use referrals, either to promote Google products or offerings from AdWords advertisers, we encourage that you take the following steps before the product is retired:
* Remove all referral code from your site(s): Please take a moment to remove all referral code from your sites before the last week of August, so that you can continue to effectively monetise your ad space.
* Replace your referral ads with AdSense for content ads: If you have less than three AdSense for content ad units on a page, we recommend replacing referral ad units with standard AFC ad units. This will minimise the risk of decreased AdSense earnings when the Referrals programme is retired.
* Run and save all referrals reports to your desktop: All Referrals reports will no longer be available at the end of October.
We appreciate your patience during this transition. If you have additional questions, please visit

Thank you for your support of AdSense Referrals.
Yours sincerely,
The Google AdSense Team
