Footnotes:

  1. So some people apparently find it useful to host "echo" services which simply reflect the query back to the sender. They act like a mirror. So when Christopher Muclumbus asks them for the software they’re running, it effectively asks itself without knowing that it does that. That’s what those "Christopher Muclumbus" entries are.
