Restrict Certain Subdomains for users

[PlanetCloud]

I'm well aware inspect element can be used to get around this but at least users cannot accidentally register sensitive domains. See this topic:

and the JS would be like "Whoops this is taken" or "Contains blacklisted keywords" before submit.

If then someone were to register the sensitive/reserved keywords with inspect element or other ways.. we can blacklist their IP instead or something, as we now know they're malicious.

if only I have time and motivation to finish this
