I still think that any subject, even the aforementioned could direct people to an awareness campaign, so even that example doesn't quite stand the test if you ask me...
I'd imagine that people that want to host that kinda stuff aren't hosting it on a domain that makes it obvious.
I can see that you're not coming at this from a negative place, I think we both want what's good in the world, but I can't think of an example that can't be turned round and used in a good way.
Like you said policing content is difficult, so banning words is just pointless and overreach imho because it's assuming the intent of the use of the domain before it's been used.
I mean... What's hosted on the EMD for the aforementioned subject? I don't dare to type it in
