And your phone and postal addresses are listed *where* that Joe Aussie-Sixpack 
is likely to be able to find? 

(Hint 1: If it's on your website, they can't find it.) 

(Hint 2: Mortal users have never heard of WHOIS or similar services) 

And what are the chances that after 3-4 days of unreachable, the user will 
simply conclude you've gone out of business and you've lost a customer/reader 
to a competitor?
