G'day Kauto,

We've had a report of this site being used as part of a mule recruitment
run:

AUSCERT#2008ba020

    Type:               mules
    Org:                not_selected
    URL:                http://88.255.94.87/job/

    Current status:     down
    Reported:           Mon Feb 18 14:52:27 2008
    Closed at:          Mon Feb 18 15:40:13 2008
    Total uptime:       < 1h

(ignore the references to times above - there could be many reasons as to
why our system closed the incident for us)

I've got a couple of samples of the spam mule recruitment email if you
want them.  We've not taken any action against the site.

Hope this helps,
