Wanna get a good idea about why asking “who would do such a thing” is not an uplifting question to ask about events like Spitzer?
Check out these sites:
http://www.google.com/search?q=emperors+club
Think they benefited at all by those curious enough to go find out about Emperors Club’s services?

Two domain name variations on Emperors Club put those sites in the top 15,000 for a couple of days. That usual equates to 50-90K unique users per day.
Wanna still get at the content like many others did that day? Use the wayback machine.
Think I’m making this up? Strange correlation here. See it over a longer period to see archive.org traffic…

So, methinks Spitzer isn’t the only guy looking for an escort. If I dug down far enough I’m sure I could find out who actually went to these sites during this time.
Also interesting note is that EmperorsClubVip.com was hosted by Homestead.com, an Intuit company. So… are they involved in the investigation….
Enjoy
