Not only does YouTube search on "no credit cards" without the quotes even, but the term trended to the point it's in the search suggestion list.

ADDED: Just noticed it was the comment area, not the search, and sure enough got a "Error, try again " - I'm guessing it's anti-spam in nature, hard to say.
