How come you are not using any #captcha here in this website?

I moved away from captcha because that's one reason why people do not register. As a website user, I hate captcha. I find it annoying specially when I'm unable to read the captcha texts.

I know that all spam cannot be prevented but I put some logic to fight at least bot spams. One logic I had is a timer that checks how long the register/post/comment was completed. Then I have a parameter for each actions that determine if it's a spam. For example, if the registration took less than 5 seconds... I consider it spam and the action does nothing.

There are other logic I implemented. If you google captcha alternative, you'll find some suggestions such as the honeypot.
