Yes, but I deliberately did not present the question with this degree of

what little fun it offers comes from clarifying the issue.

Yes.  In the old days (which is only the late 80s in this case) I think
all newsreaders would require some action to see that part of a message
after a form feed, so that was how spoilers were put "below the fold".
