Subliminal advertising in spam?

Nick FitzGerald sent me a great example of subliminal advertising in a spam message. At least that's what he thinks the spammer might have been up to. The spam contains an animated GIF with four frames. One of the frames (which contains the actual spam message) remains visible for 17 seconds. The other three frames are displayed for 10ms or 40ms, and each of those contains a little random noise and the word BUY in random positions.

Was the spammer really hoping to make us fall for his pump and dump scam with a quick flash of BUY on screen?

Here's the actual GIF with the animation in place (watch out you might be forced to BUY :-)



And there are the four separate frames:

10ms
17s
40ms
40ms
