YouTube showed me a "this household watches suspiciously many videos" once when the provider moved us behind a CGNAT (because 100 households were suddenly watching from the same address, not just one).

It also messes a bit with geolocation, we frequently teleport to different places within the country.

Yeah, but in this case, the negotiation between the ISP and YouTube typically ends with the IP being unblocked. It's not like when one household is actually watching as much as 100 people, when the IP stays blocked.
