I can't tell if this is a "collection of common uri to test" or "screwed up beyond belief" searches. In too many cases (and G and Y do this as well, just not as agressive) it looks like the SE is testing the site for the underpinnings.
All of my sites are hand made. No wp, Joomla, etc. CMS style systems, yet all are being tested for those. What can you do? 403 is my response.
