Why would it (legally or not) be Namecheap's job to curate the content? What about the server the content is hosted on, its CDN, its DNS servers, its domain registry (not registrar), or so many other layers?

If a website that incites violence can be taken down because of a single violence-inciting remark, then people will just post violent remarks on their enemies websites and proceed to get them taken down. As an administrator, whether of a domain, social network, forum, or services on other layers of the Internet, it's unreasonable to be held responsible for every single thing done by your users. That doesn't mean you have to let them do anything, but when a problem occurs, the first step should not be to start taking down websites and servers, instead of looking for a more reasonable solution.

At this point it's turned into a game of hot potato. No-one wants the bad press of being "the one who said yes".

They need to find a registrar whose market position is built on taking a stance. Namecheap ain't it.
