> Every other list I subscribe to is moderated.

Really?  Are you sure that they don't simply restrict posting by
requiring a subscription to post?

A classic moderated list requires each individual message to be approved
by a human before it is distributed to the list.  This requires much more
operator overhead.  (and you think posting times to the list are extremem
now...)

There are many moderated lists, but most of them are very low traffic
lists, usually for announcements etc.
