Today I went to the Polar site to pose a speed sensor problem. (They make endurance training monitors & such.) Having never posted I of course have to register. In addition to the captcha, they also have an image with a question. Not text , image. You have to answer the question, which in this case was 4+3 = , filled block = 7. A really good method to additionally thwart the bots?
