From what I can gather at least what I am seeing now. Is that you can't actually have your keywords in your url. For the past couple of years I have had success with ThisThatOnline.com. Logically people will naturally link to you as ThisThatOnline.com hence it will suggest to the algo's that you should rank for This, That, and This Online, and That Online without incurring a penalty since its perfectly natural to link to a site with its full name.
Now it seems you can't do that anymore. Your site needs to be completely unrelated with a subdomain or a category about This and That. Particularly if its video orientated.
Somehow this logic makes sense to G. Don't build a site about This and That with the keywords in the domain.
