Youtube ads getting through Pihole

This is normal and expected.

@ChromeNewt

I'm expecting that my pihole should be able to identify the adverts and drop them off, or filtering unexpected extra connections, since there's always a pair of requests in the query log that are veeeery subtly different.

Pi-hole only sees DNS requests for domains (in this case, the Youtube domain).
Pi-hole can completely block the domain, or allow the domain. There is no third option.
