The "kitten CAPTCHA" could then take countermeasures:
1. Apply transforms to the images. This would require spam bots to perform much harder processing.
2. Use a larger pool of images -- after all, this is the Internet, a communication medium used primarily to exchange pictures of kittens.
Of course the spammers would adapt. But CAPTCHAs are not one-shot solutions. A good CAPTCHA works well enough to defeat most bots, and is updated once most bots start defeating it.
