They used to be, but not anymore. They still show up on my subdomain config page. I've tried removing them from my account but always get an error . I get that error for all four of them (2.rickey.asia, school.rickey.asia, secure.rickey.asia, and w.rickey.asia).
One more thing: They don't show up as a "normal" subdomain. Instead they show up as subdomains under the root domain "."
