Changing subscription options and deleting subscriptions is easily  
locked out
by keeping the list locked and allowing only selected individuals (or  
processes)
to unlock it. Don't get me wrong, I do not advocate this strategy,  
but its what
we do on a routine basis to appease administrators here and the idea  
works
nicely, not withstanding the possibility of subscribers using a  
filter to
move such email to /dev/null.
