Re:Pi-hole – A black hole for Internet advertisements on Monday March 13, 2017 @09:24PM (#13864171)
The web advertising firm I work for has random looking domains for that purpose. The current domain generation algorithm seems to be using one to two domains a month. Although I've don't have access to any of the frontend code, I can only assume the DOM elements on the page are also obscured/randomized to an extent.

It is also my understanding that some of our boxes are here solely to proxy requests (either assets or websockets, which are increasingly popular in the field) to 3rd parties, to make sure it bypasses client side countermeasures.
