Hello, CAPTCHA!

Commenters - take note!

I have added a CAPTCHA, or Completely Automated Public Turing test for Telling Computers and Humans Apart. The goal - prevent software-based comment spam by requiring people posting comments to type in a short string from a picture on the web. Since a computer can't "read" the picture, comment span will disappear.

Hopefully, you don't mind too much. Sorry if it's a pain. :-(

  2. I AM A HUMAN, SO TELL ME APART!

    I suppose it's case sensitive. It doesn't say that.

    It's funny. My code was HRhG. It looks like argh, which is kind of how this feels :wink:

  3. Yeah. Case-sensitive. I've made it all capitals. All lower-case might be easier to type, but I think they're prettier.

    I'll also change the prompt to indicate case-sensitivity.

  4. So how much comment SPAM did you actually get to have to implement this?

  5. 10 or 15 a day sometimes... my old Spam filter caught about a third of them. The other ones were in way-old posts, generally, but still very annoying. :-P
