@My1 we tend to not trust wikipedia when making the ultimate choice. We did it in the past, but we now require an official approval from the registry (either direct or indirect from the website) or similar proof.
I’m going to research it, but any extra hint or reference is welcome. That’s why I was asking about that specific domain. I’d be interested to know more about these exceptions (specifically, how long is the list and how does it work).
We may either add them as !rule exceptions (that will take higher precedence over the *) or whitelist zm.
