OK...that's easy enough, and doesn't require compromising anything.  It just
requires subscribing an innocuous address to the list(s), and keeping track
of posted message senders.

OK...that wasn't the recipe which was suggested by your initial message,
which said the bogus confirm came shortly after you confirmed...no mention
of posting a message too.

There's also the fact that my provider's anti-spam mechanisms could well
have kept the bogus message out even had it been attempted.
