Occasionally, (most recently with the Ape page) we have a visitor create a page without putting any actual information on it. I think the reason for this is that as things are, there is no obvious way to tell that the Blue Links go to pages and the Red Links don't go anywhere unless you already know. So people click on something they think is a link and it takes them to the "Do You Want to Create A Page" prompt.
Don't know how to solve this; other than create a bunch of pages to turn those Red Links into Blue Ones.
