Spoems, or spoetry, are "spam poems" writtem using only the subject lines from spam emails. Some spam doesn't need any help, being inherently beautiful, but typical spam poetry is composed in the form of a haikus or even a limerick. This is Spoetry at its finest.
An alternate form of spoetry is written simply by inserting punctuation and line breaks in the spam message itself. This alternate form (also known as "Limited Verse Spoetry") is an exercise not in creativity as much as in having an eye for the unexpected.
The exact origins of spoetry are shrouded in the mists of time, but scholars believe that it can be traced back to medieval France when literate pranksters would steal royal proclamations and rearrange the lines to form pseudo-poetic verse.
