I was wondering if anyone else has wondered the same thing about the wierd text at the bottom of a lot of the spam, and if anyone has ever used PHP to create any cipher tools in an attempt to crack the following:
The text is simply there to get past filters or to pollute adaptive filters with good words. If you get a spam that has "see spot run" as random text in it, you're filter may not mark it as spam. If you manually mark it as spam, your filter may think see, spot and run are spam words and start flagging legitimate emails as spam which may cause you to turn if off, lighten controls, etc, and possibly allow more spam through. Win-win situation for a spammer.
Although, you make an interesting point and there's certainly nothing saying the text couldn't be used for what you describe. There could be messages hidden in the "herbal viagra" image, also. (that line will probably get this marked as spam for a lot of you, heh). So keep working on what you described; it could be interesting either way...
