I can’t imagine that happening with today’s systems. Yes, it’s theoretically possible. It just seems unlikely that they’d go through the trouble of denying service to someone who didn’t fetch data from one specific domain but did get it from another.

Install a Pihole server on your network. It’s a DNS filter. When a client tries to access a domain that has been blacklisted (ie a known ad or tracker domain), it denies the lookup.

On my roku homescreen it just has an empty placeholder where it tried to put the ad, but my Pihole server denied it.

PiHole.

But how will I bring up my NAS in conversations at parties?
