When an entity only advertises a domain name www.domain.com rather than the URI http://www.domain.com/ http://www.domain.com/ then as far as I am concerned, I have been invited to query that server concerning the services it offers, namely: a portscan. For instance the page at http://www.amazon.com/ http://www.amazon.com/ contains an advertisement that simply says "amazon.com". So I should scan it to see what they offer. It might be http / https / irc / echo / heck even a shell for all I know. If it were "1 Amazon Street" I would be perfectly entitled to arrive at that building and see if any entrances were open to the public. It might say "Amazon club card holders only" on a door and I might be asked for my card should I try to gain entrance. It would only be "criminal" if I decided to gain entrance despite such constraints.
