but just for fun, i'll continue this train of thought, you could use PHP's GD library to create images dynamically that contain the "negative keyword text" that you don't want the adsense spider to pick up on. thus you aren't really sending different content to the mediabot or to users or hidin content, etc. of course this would lead to other problems with real spidering...
If you really need to do this, I would have Javascript write out the text, rather than use an image. There are various reasons, but the main one is that, even with CSS, the letters in the image will not always exactly match the surrounding plain text.
