I would like to hear from members of the list how they are
dealing with this sort of situation.



If you don't need to read the mail going to that account (i.e. not a  
sales person or someone who had direct relationship with a vendor,  
etc) then just return a 5xx error in session for attempted deliveries  
to that user.


Removed users don't make good spamtraps.  Users who never existed  
though, can often be useful.

hmmm, why not just remove an account? this way your server will reply 
550 User unknown, and make sending side bounce the mail effectively 
notifying postmaster/mailing list manager that this account has removed.
