new stock spam

[Joe Zitnik]

For the last few days, I've been receiving stock spam, same format as the other stock spam, except the spam is a gif image.  Some randomstringofletters.gif, and a bunch of text.  The random text will show up at the bottom of the page.  The ones I'm currently seeing are for Golden Apple Oil and Gas.  Because the subject is always different, the name of the gif is always different, and the text is always at least a little different, there's no way to consistently stop these, is there?  I've been feeding them to bayes, but they're still slipping past, I'm guessing because each one is so dissimilar from the next.
