Captcha time!Well folks, here’s a meta-blog entry for you. And it’s related to Artificial Intelligence and Cognitive Science to boot! I’ve been having problems with spammers. They come and leave comments like ‘Very nice blog. Why not check out my great Viagra site at www.badsiteyoudonotwanttovisit.com.’ I had a great scheme that diverted spammers to expensive downloads of Microsoft operating systems, but it depended on knowing their addresses. Now spammers come from so many addresses that I can’t keep up with making the list. My new solution is to use a captcha. Like everything else in this crazy business, captcha is an acronym for ‘Completely automated public Turing test to tell computers and humans apart’. A mouthful for sure. A captcha basically asks you to answer a skill testing question. Sites like Yahoo! and Google use them to stop robotic computer programs for signing up for free email accounts. Big sites have complicated captchas that are hard for computers to break. My little blog has an easy captcha: read the mathematical question and type the answer. I suspect that even the most math-phobic human could answer my captcha. So, folks, I’m sorry to inconvenience you, but please type one character into a field to prove you’re human when you leave me a comment. Oh, and here’s some more captcha tests to play with if you’re so inclined. I like Bongo and Pix.
