He owns the domain toad.com. He runs the mail server at toad.com as an open mail relay, allowing friends who travel to send e-mail through his server. In March 2002, this was in the news since an Internet virus had that mail server hardcoded as one of the open mail relays it would use to propagate itself. In October 2002, John's ISP, Verio, cut off his Internet access because he refused to stop providing his service, even though John's relay was programmed to be essentially useless to spammersmers and other senders of mass email.
