One response suggested that this sort of blocking could be circumvented by each publisher using a random valued subdomain. The text in question is here:
What strikes me about this set up is that it would work for non WebRTC based ads as well. Either the Ekr found a new way to beat adblockers, or we are missing something important in that discussion. I was hoping for feedback from individuals with more experience in this domain.As a thought experiment, consider an ad serving design in which publishers
include ad content as they do now but instead of having it sourced from the advertiser's origin, they instead stand up "<randomvalue>.publisher.example.com" and point it at the advertiser's IP addresses (via an A record to the advertiser's name never appears). This would have a similar cost/effort structure to using data channels and would similarly not be blocked by current domain-based ad blockers. What would our expectations be here?
