First off, I hate it. Specially when it throws you those weird numbers. so I go for the simple images that don't confuse many people.

I would go for smaller and easier versions of Captcha if you must. For instance simple 2+2= or 4-2= would serve the purpose as well as confusing images of finding traffic signals etc.

I think bots are made to actually get by that somehow.

I don't care for Captchas because some of the numbers/letters are illegible and I take too much time looking at the next set. Doing the image ones where you check off the boxes of whatever takes forever and sometimes it makes me do it all over again and that's frustrating. I don't have a better option than Captchas though because our spammers get through anyway even though they aren't always bots.

We have the numbers and letters captcha, although I hate captcha of any kind really.

I hate them especially when you can't make out the characters but mine uses a built it one.

I think most places use a built-in captcha 

Captcha is boring. Rather than Captcha, I would find way to block spams and bots. I know lots of people don't like Captcha.

I've used reCAPTCHA until recently, but got put off from doing so from another forum due to concerns about the amount of data transferred to Google:

• • The website where the CAPTCHA is integrated
  • User agent of the browser
  • IP address of the port
  • Screen and window resolution
  • Language set in the browser
  • Time zone
  • Installed browser plugins
  • It is checked whether a Google cookie has been stored in the browser - if not: a cookie is created

As a result, I reverted to using http://textcaptcha.com/  which generates random questions for the end user to answer.
