This list apparently does not track much of the active spoofed  
announcements.  This is understandable, as this tracking remains a  
difficult task.

Some of this information is incorporated within one of our temporary  
lists, but not exclusively.  The level of this activity is rather  
disconcerting.  Perhaps there should be a list dedicated for this  
purpose for use beyond email, which appears to be the purpose of most  
but not all such announcements.
