Brad, do you think spammers really do that just to increase their
address count?  I've always assumed that they were just harvested in
the usual way.

It is if, for example, the problem is that somebody is using fake
bounces with a spoofed from address to beam spam at somebody via your
site (one aspect of the so-called backscatter problem).  In that case
all the recipient has is the list-owner address (and of course
postmaster at your.dom, but if that isn't you personally, you probably
don't want that person getting upset with you!)
