Some technical notes on the situation:
https://www.hpmor.com currently serves a 302 redirect to https://www.lesswrong.com/hpmor (and this response is being served by CloudFlare)
the domain is registered with Namecheap
the DNS servers for the domain are those of DreamHost (and thus probably the actual hosting of the site until recently was provided by DreamHost)
