I got this nice email at work the other day:
i am hoping to share a laugh with the person who did it, it was on a site that gets millions of hits a day then i gotta give 'em hell for doing it on my network.Hello Sir/Mam,
I am contacting you because of a serious offense originating from an IP
address which seems to be located on your subnet.
I am an administrator of (site). It is heavily frequented and used as an information source by countless people around the globe. For the matter at hand, yesterday, visitors to (site) suddenly found the frontpage defaced with offensive images, known as Goatse.cx images. The incident can be tracked here:
This resulted in the offensive images appearing on the front page immediately. We have temporarily banned the IP address in question, but as this is a serious matter that has affected possibly thousands of our viewers, we sincerely hope you will be able to track this individual, and take any action you see fit to address his/her behaviour.
Thanks for your help,
