Understood.  One reason I chose a recent sample was to try and avoid 
missing accounts due shutdown.  Those tests were run within 24 hours 
of the time I received the email.  Of course, we have no way of 
knowing when the spammer set up their software, or how long they've 
been using that particular account.

I'm not sure which upsets me more: that people are so unwilling to accept
responsibility for their own actions, or that they are so eager to regulate
everyone else's.
