Google AdWordsAdvisor has informed us in a WebmasterWorld thread that soon AdWords advertisers will be able to opt out of the AdSense for Domains network.

We are working on making it simpler for advertisers who don't want to show on domain sites or error pages to exclude them. In the meantime, if site exclusion does not seem to be working for you, you can write into support for help.
Reportedly, this is coming. The big question is when?
The AdSense for Domains program has always sparked huge debates in the community and industry. So this step by Google will be a much desired one and an overall great move for advertisers.
