Now that I’ve relented in my crusade against full text RSS feeds, I’ve decided that Captchas are now my biggest pet hate. CAPTCHA stands for “completely automated public Turing test to tell computers and humans apart” and are the usually unreadable string of text that many sites now ask you to enter before you can leave a comment.
Weblog Tools have written a very good post critisicing Capthchas and I agree with every point made. I really hate these as for some reason I find them really hard to read, and totally unnecessary as services like Akismet do a very good job of capturing spam.
Adding Capthchas also put an additional barrier in place that could stop a reader posting. If you really want to check that your poster is human then check out the Math Challenge Plugin that asks a ‘simple’ maths question before a comment is posted. You can see a similar solution in action at SEOpedia.
