One option would be to wait until a Search Engine Anti-Thesaurus [hastingsresearch.com] gets adopted. The other option would be to cloak the page. I know that seems like an evil word to many, but it certainly is a legitimate solution for your particular problem. Simply deliver a version to spiders that has all occurences of the word free removed from the copy. I don't see how even an extremely anti-cloaking engine like Google would have a problem with it, since you are doing it to prevent trasffic rather than gain it.
Now it is more clear. :)
