Here's an idea I've seen implemented in some captchas: Instead of generating an image of text that most people have to strain to read, instead, generate a relatively cleaner image but instead of typing that in, have it ask a question to be answered. "What do you get when you add 2 and 2?" etc... Would that fare better?
