I'd certainly look for contact us information, or an email somewhere on the site.

Make sure also that you are not into a review blog that is completely ran by a hosting company as a fake site, etc. There's plenty of these (you can see the follow/nofollow links to get an idea) and go from there. Most serious bloggers you will have to contact them via email to get listed with them, and they will most likely charge something.
