Yes, I often leave messages with anon users, and often have to end up blocking them just to tell them that I've left them a message.

BTW, the way to leave the message on the archived talk page is by going to the edit page directly: The content of the message you leave there doesn't really matter, because the "You have new messages" popup will lead them to their Message Wall, not the archived talk page.
