> I don't see how it had an impact on revenue if ads weren't displaying

1. browsing hacker news sees interesting article, uses ad block.

2. posts link to Facebook

3. link gets propagated across Facebook and clicked by 1000's who do not use ad block

4. x1000's

You can think of ad block users like carriers. They show no symptoms, but could be the man vector for distribution of your content. So they may have a value that can't be measured in ad clicks.

The interesting question is if they saw a subsequent fall in ad revenue indicating a correlation between ad block users and more ad revenue.
