yeah, if you're talking old style ooofbots.  Those Listserv can spot
as repeats and clamp down on 'em.  The newer ones are infinitely
customisable so each ooofbot reply is slightly different, which means
LISTSERV can't spot 'em.  Had one, oh, three months ago on a large
professional discussion list running on 1.8d.  What a mess.
