Interesting to see vox.com in there, being that it's just a blogging service that could contain a legitimate blog. Why all of vox.com, but not all of wordpress.com, livejournal.com or blogspot.com?

Because in those urls the account is a subdomain, so for them a site can be defined as e.g. x.wordpress.com. I don't want to get into representing sites as regular expressions if I can avoid it.
