Seattle City Light has a nice opt-in green energy program. Which is cool and all, but look at the form at the bottom of the page. Particularly the hidden form variable autoCode2. Lamest captcha ever.
The captcha at the end of it is in plain text. You can copy-and-paste it directly into the text field. Worse than that, it's set in a hidden form variable, which strongly implies that you could set it to be anything you want. Basically, it completely fails to provide any of the bot-protection that are the entire point of captchas. (Not that they actually work all that well at the best of times, but that's another issue.)
