Spam incident today over Gossip mailing list!

>[...] Now Available FREE

Gossip is a "only members can post" mailing list, and to join you have
to go through a confirmation process. Until today's incident, I would
have said we were pretty much spam proof because of that. (For those
looking at the gossip archives, there is some spam mixed in, but none
of that went over the actual list -- it's all an artifact of
Mail-Archive getting spam with extremely funky headers causing them to
archive with gossip). Anyway, I am shocked! At this point I have no
idea if this is some fort of automated attack on Mailman mailing
lists, or if we have a spammer manually targetting gossip. I've of
course removed the spammer from gossip. If there are more incidents, I
guess I'll have to figure out additional measures. This is definitely
a new low and I'm sorry that this garbage got through.
