Microsoft will use equipment located in California and other states

I have been meaning to blog about this for a while now. When contacting the Hotmail mail servers to send email your mail server will be presented with strange message in my opinion.

First find the servers which receives email for the hotmail.com domain:

dig mx hotmail.com

which will return something like the following:

hotmail.com.            3600    IN      MX      5 mx1.hotmail.com.
hotmail.com.            3600    IN      MX      5 mx2.hotmail.com.
hotmail.com.            3600    IN      MX      5 mx3.hotmail.com.
hotmail.com.            3600    IN      MX      5 mx4.hotmail.com.

Now try contact one of these on port 25 (just like mail servers does):

telnet mx1.hotmail.com 25

Notice the greetings message from the server:

Sending unsolicited commercial or bulk e-mail to Microsoft's computer network is prohibited.
Other restrictions are found at http://privacy.msn.com/Anti-spam/.
Violations will result in use of equipment located in California and other states. 

Bringing it to peoples attention that sending unsolicited commercial or bulk e-mails is prohibited is fair enought even though I doubt many will read it :) But is it really nessesary to threat to use equipment, and why is California emphasised?
