References a web site and says " (Site is now defunct and cannot be accessed.)". And indeed, no copies in any of the usual archives. And why? The internet archive says _This URL has been excluded from the Wayback Machine._
I.O.W., the domain has been taken over by somebody else, and the Wayback machine has retro-actively decided to censor the information.

That’s just what they _want_ you to think.

That was one decision I did not like. The archive decided that, if anyone ever puts up a robots.txt that forbids archiving, then all archives up until that point are also removed, without regard to who owned what.
It should have at most covered a certain period of time, with a requirement to specifically request removal for more than that.
Whoever buys [straightdope.com](http://straightdope.com) when the site disappears should not be able to erase the archive.

It’s a “robots.txt” issue and was probably put in place after a DOS attack.
