Google Fishing
I recently found a lot of 404 queries in my error log coming from 72.14.199.94. A search online shows that this IP address is coming from Google.com. It looks like that Google is sending words to find unpublished areas of this website.
I guess this is one way for Google to build up their search database, however, if I wanted to make certain areas public, I would have put a link on the homepage or in the sitelink.xml. I guess the lesson here is to use complex directory names to hide from Google.
