Sometimes I pretend to be a search engine robot to get access to "subscriber only" web pages, or just to get a plain and simple view of a page that isn't cluttered with moving animations and other irrelevant crap.
Lately I have noticed that some web sites require cookies to be turned on, even if you are a bot. What is the purpose of this? Why would a search engine robot need to accept cookies? Or is this just because the guy who designed the web site screwed up?
