E-mail and other forms of spamming have been used for purposes other than advertisements. Many early Usenet spams were religious or political. Serdar Argic, for instance, spammed Usenet with historical revisionist screeds. A number of evangelists have spammed Usenet and e-mail media with preaching messages. A growing number of criminals are also using spam to perpetrate various sorts of fraud, and in some cases have used it to lure people to locations where they have been kidnapped, held for ransom, and even murdered.
In early July 2006 there was an enormous increase in unsolicited messages from a spoofed address with approximately half a dozen random letter subjects, containing nothing but three lines from JRR Tolkien‘s The Hobbit. This follows fairly closely another similar form dubbed “discordian poetry” that appeared to use a random word generator of the same. The messages had no attempt to sell anything; it was theorised that this was a script kiddie ineptly running a spam suite. This was confirmed when shortly afterward the same format messages began appearing with image files overlaying the text (a common spam technique). It is suspected to be a variation from the same source and image overlays will begin appearing.
