Google has published a killer robots page. To be precise, they added a "killer-robots.txt" file to their main search page.
(That's a parody of the robots.txt file, which lets a web site control some uses of its content. So if you look at google.com/robots.txt, you see a bunch of short commands, like
User-agent: * Disallow: /search Disallow: /sdch Disallow: /groups Disallow: /images Disallow: /catalogs Allow: /catalogs/about Allow: /catalogs/p? Disallow: /catalogues
So what does http://www.google.com/killer-robots.txt reveal?
User-Agent: T-1000 User-Agent: T-800 Disallow: /+LarryPage Disallow: /+SergeyBrin
Yes, Google is keeping an eye on Skynet. At least for self-defense.
