I've seen mail containing ONLY the text mentioned above, in which case it'sstrange. From the original mail I got feeling that the mails also contain mentioned text only...
The original mails I clipped the original obfuscation text from were using it to hide a phishing attempt. I have not seen it used with no other content in my mail stream. However, from time to time I see a mal-formed spam that lacks content and just has the formatting. Perhaps that is what you are seeing.
