   I thought most of them just keep using new addresses. I set Thunderbird   
   to delete them but just to clear any other recent Spam from them - they   
   often seem to send a bunch of messages over a short time and never seen   
   again.   
      
   Of course Thunderbird has the major failing that it is messy to block an   
   address in all newsgroups because the default only applies to one newsgroup.
