I caught this article a few days ago on something similar to what I got on YYZtech.ca a few weeks ago: spam without any urls. The author has two theories: 1) they are trying to train automatic spam filters to allow certain words – that will be later used from spamming, and/or 2) they want to get the e-mail addresses where the spam was sent from white listed, again, to use for “real” spamming later on.
