To the best of my recollection some of the lists to which I am subscribed refer posts to moderation where the subject list is, "Re: Contents of main digest...", thus, in the main, catching posts to which one may have replied in haste, by simply hitting the 'reply' button. such a policy would have caught the post by Bob Dove.
Aside to Bob Dove, top-posting is placing you reply above the quoted material, the usual practice is to cut the quoted material and then reply underneath the quoted material, or to interleave them into the quoted material. see: http://www.catb.org/~esr//jargon/html/T/top-post.html http://home.online.no/~shughes/a57998/quote.html which may be of some help.
