I think we're really getting into wild speculation territory here. No one 
will bother hacking the code to automatically get new free mail accounts 
(this requires staying up to date with some range of mail service's cgi 
interface for their join function), automatically join any mailing list they 
find (same problem as before, coupled with having an automated way of finding 
lists to plunder), then going through the usual email confirmation step (ok, 
not hard if your mail service lets you pop mail from them). 

No one is going to bother implementing and maintaining this attack while they 
can grep addresses straight out of Usenet, off the web and out of DNS. If at 
some point in the future, those sources dry up, then it might be time to 
rearm. If there's compeling evidence that private archives and voluntary 
address obfuscation methods are failing, then it's time to rearm. But let's 
just keep in mind that this will always be an arms race, and that at the end 
of the day, it's only junk mail.
