At Postmodern.com (my own site, as distinguished from GreatCircle.com,
which hosts business and software-related lists, including this one), my
lists are typically music/entertainment/recreation-oriented, and I don't
see any reason to use them to disseminate virus warnings, hoax alerts,
or the like. I filter on "virus", "warning", and various other things
in the subject line, and if a message is trapped it is returned to the
sender with this note:
> Please do not send chain letters, petitions, virus warnings, urban
> legends, appeals for funds, hoax alerts, forwarded lists of jokes, etc.,
> to mailing lists hosted at postmodern.com.
> Your message was blocked by the list server from going out and
> is being returned to you.

If it was not trapped the sender gets the letter minus the second paragraph.
