How do you plan on blocking ad servers with DoH?

With ublock origin. DNS level ad blocking is rubbish and mostly circumvented by providers now.

I heard that ads were able to circumvent DNS by using canonical names.

But uBlock origin and PiHole both do CNAME inspection to block this.

Is there other ways that ads are circumventing DNS ad-blockers such as PiHole?

I have found that rather than finding a way to sneak ads in, most non browser apps will just detect that the ads are missing and throw up an error refusing to display the content.
