Ad providers are obfuscating domains to bypass blocks. Currently only ublock origin deobfuscate and block based on the original domain.(It is supported on firefox only anyway) But after the change... I guess no one on chrome can do. And ad blocking will be totally useless at that point.

Brave also does the CNAME uncloaking like uBO.

What about first party domains

Behavior-based blocks take care of those largely. I think only Facebook is reliably staying ahead?

If you mean ublock origin cosmetic filters, yeah facebook is really putting up a fight. The status quo has been randomized css classes, identical html structure, interspersing hidden junk characters in between the "Sponsored" text, and the latest I've noticed, anchors that link to # until you hover over, preventing blocking href=^/ads. That and turning on or off or changing behavior between users and regions makes collaborating on rules really difficult.

This has me surprised because most of these changes are not very complicated and I have always wondered why these methods weren't more widespread. To me defeating ad blockers seems easy as long as you're willing to play cat and mouse (and if your income depends on it I guess you are)

Now I’m imagining monetizing an ad-blocker by selling CAPTCHA services based on users training an AI to recognize Facebook ads.
