You’re over thinking it, if you want to block those two domains then just add them to the block list that should block them. The documentation you read about whitelist, blocklist and why you can do it one way and not the other is to do with how rules are processed, in your case it’s not relevant if all you’re trying to do is block those two domains. Whitelists are processed first, and if there is a hit then the domain is allowed. If the domain isn’t listed in the whitelist then the blocklist is tested. When a domain is tested the subdomains are iteratively removed, thus if you whitelist a parent domain it will always hit the parent during testing, and never get tested against the child in the blocklist. Hope this makes a bit more sense now.
