Not that I saw, no. What I read of your message indicated that
the virus had infected a normal user and pulled a message out of
their sent folder, which would not have had the Approved: header.

Most moderators I know of don't need to use the Approved: header,
because they themselves are not moderated on their own lists. But
then maybe you know more moderators than I do.

I still think it's a lot of work for a virus to go through, but
when they do finally run into a moderator that uses this technique,
there is a high chance of successful transmission to a large number
of other targets.
I guess the question is when does the probability go up enough
that the payoff justifies the amount of input work?
