Spammers often use automated tools for posting messages very quickly. WorksForWeb added CAPTCHA in all their products including iRealty, especially for protection of a website from such attacks.
CAPTCHA is a Completely Automated Public Turing test developed to guarantee that a human generates the particular response, not a computer. Humans can easily pass this test but computers will hopefully fail.
A captcha contains on a picture with the distorted or rotated text.
Currently, the captcha is integrated on Contact Us, Contact Seller, Tell Friend, Contact User, and Registration pages. The admin can easily turn it on/off easily.
