I found this article fascinating. It really is amazing what spammers do to try to get their emails past various spam filters.
The Fight Against Spam - New York Times

TO the antispam researchers at MessageLabs, an e-mail filtering company, each new wave of a recent stock-pumping spam seemed like a personal affront.
The spammers were trying to circumvent the world's junk-mail filters by embedding their messages — whether peddling something called China Digital Media for $1.71 a share, or a "Hot Pick!" company called GroFeed for just 10 cents — into images.
In some ways, it was a desperate move. The images made the messages much bulkier than simple text messages, so the spammers were using more bandwidth to churn out fewer spams. But they also knew that, to filters scanning for telltale spam words in the text of e-mail messages, a picture of the words "Hot Stox!!" is significantly different from the words themselves. |
