If I search Google for "web tools" here
http://www.google.com/search?hl=en&q=web+tools
the #1 and #2 sites are no longer available and have a redirect. Why would Google allow this?

They still have good no of backlinks and you can always report that.

#2 seems to just redirect to a different page on the same domain, which is nothing out of the ordinary, and #1, well, doesn't look very useful, but "Sorry we closed shop" must look like any other content to a semi-literate spider.
