The article is a bit naïve in that most popular sites will get slammed by exploit-seeking bots. At my previous employer I had a setup to silently log known exploit URLs that reached the 404 handler, and blacklist the IP if more than a few showed up from any one IP address. Also, a 301 redirect from the old location of a page to a new one goes a long way towards fixing stale SERs and bookmarks.
