I had mentioned this CAPTCHA in another thread, but unfortunately I didn't know what it was called, or where to find it again. I came across it yet again a few minutes ago so I figured I'd bring it up here. This CAPTCHA focuses on proper grammar and spelling: http://www.defectiveyeti.com/iacaptchas/
What do you think about this one? As rsnake had pointed out in the topic about blindly inserting words into content (the one where "African American" was substituted for "Black" on a Baseball calendar) it's usually difficult for a program to understand the context of a word. True, Microsoft Word's spell checker and autocorrect can, in most instances, notice the incorrect use of a word that may be a homophone such as "there", "their", and "they're", but there's many times where it suggests things that aren't right, or very odd. With that in mind do you believe this CAPTCHA to be an effective measure against automated procedures, or do you see it as easily circumvented?
