I don’t get as angry about Captcha as I used to, but on occasion someone asks me why I don’t like it. I figured I’d post this list here so I can have something to reference, instead of having to brainstorm everytime I’m asked the question.

  • Most people hate filling out Captchas.
  • It doesn’t stop human spammers (they fill out your form manually).
  • Spam software these days can break through simple Captchas.
  • If you make your Captcha harder, you may block legit users.
  • Blind people can’t get past Captchas.

So what is my least favorite feature in ColdFusion? <cfimage action=”captcha”> 😉
