Sounds good to me :)

I think that people have shown that random words are pretty  
ineffective (e.g. John Graham-Cumming at 2004's MIT Spam  
Conference).  Random paragraphs (those news clippings and the like)  
are a bit more effective.  I think that image-based spam is clearly  
far superior to any sort of random-word technique, though (although  
some of the image-spam also has the random words - I'm not sure that  
really helps the spammer, though).
