Also ad block should not break log-in process. I recently discovered that I could not log in to a web site unless I disable ad block. All core web site functionality should be tested to work with ad blocking. Unless you really hate your users.

Adblockers block Google Analytics, which is a different script from the ones that are served as part of displaying banner ads.

GA has an enormous set of capabilities for measuring user activity and e-commerce, especially because Tag Manager lets you assign trackable events anywhere you need to on the site.
