[list of random path names snipped]

	This seems to be a very wrong and bad thing to do. Google searches URLs
because a human gives it permission to do so, for example by linking to that
URL. (What purpose does a link have other than to be something to click on.)

	What gigablast seems to be doing, on the other hand, is trying to open
every window in a house in the hopes that it will find one that's open. It
has no invitation or permission to do this, and I would consider such
behavior inappropriate.

	You do not have the right to make requests of other people's computers
without their permission. You can certainly argue implied permission in many
cases -- for example, if Ford registers the domain ford.com, and assigns an
IP address to 'www.ford.com', you can certainly argue that they have invited
the public to access that URL because that's the normal reason people create
such things. However, you have no implied permission to try numerous
combinations of random paths on the end of that in the hopes that you'll
find something Ford did not invite you into.
