You could add a rule to allow ads.js for each site's domain that's using the method as we've described, but a site could easily dynamically cycle through the thousands of file name combinations contained within EasyList.

Then simply allow all scripts on the domain to load, only blocking 3rd party scripts.

It is a cat and mouse game.

I couldn't agree more and it'll probably remain that way for awhile longer.

3rd party scripts can be included via a CNAME record at the root domain level.
