Then again, I belong to a fairly esoteric list that requires a conversation with the moderator in able to even be able to join the list. Part of the conversation is stating that you Will Not Spam. About one in 5 new members is a spammer, and gets deleted from the list after their first post (or first 3 simultaneous posts) all of which are spam.
