You can post a topic asking for a domain or the like to be redacted, but it really doesn't make much sense.
DNS will show where a domain is hosted unless (quite-significant, especially if email is needed) effort is made to completely hide where the site is hosted. Even then, attackers don't necessarily care where it's hosted, as most attackers are just using bots that go looking for things like unpatched Wordpress installations to break into...those methods of compromising a site are mostly the same regardless of hosting company, and the mitigations are also mostly the same (install updates when they come out, don't use software from dubious websites, etc.)
