Roosevelt Campaign - Why Make Pages Appear to Be Worked On?

Does anyone know why, in many parts of the Theodore Roosevelt campaign, someone has put 1-3 words on each page to make it indicate that it's "In Progress"? When I first started working on this campaign a few months ago, I thought staff had done it for some reason. After a couple of months, though, I no longer thought that.

Someone, or several people, went through hundreds of pages typing 1-3 words from that page, often with spelling errors, and then saving each page. Why?
