No, it's more comparable to the jerk who not only doesn't stay at home
with his cold, but actively walks around the workplace coughing and
sneezing without covering his mouth/nose with a kleenex, spraying people.

The reality is that it fails the "if everybody did this, would it be a
good thing" test.  While some "B&D" is common sense on the receiving end,
this does not make it any more correct for the originating site to let it 
keep happening.  If every PC on the Internet (conservatively, let's
assume a billion devices that are sufficiently sophisticated that they
could be infected) were to send you a single packet per day, you'd be
seeing over 10,000pps.  That should suggest that the behaviour is not
something to be encouraged.

My locking my doors does not mean it's okay for you to check if my door
is locked.
