Auto-responders are pure evil, but I don't think list subscriptions are
in the same boat.  I remember back when lots of stuff required no
confirmations of you email address, and my college roommate thought it
was extremely funny to sign me up for all kinds of random stuff.  Like
m4m dating groups.  It was a little disconcerting (for me, anyway) to
find occasional emails with attached pictures of some guy's erection in
my inbox...

You win again, gravity!
