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.
"...I want to thank you and your team for all the new modules in the past year you have offered. Many other website companies don't continually keep adding new things to their services. It makes you guys stand out. Keep up the awesome work."
"The price, as well as the price for custom work, is affortable. The response time on questions is unusually fast and clear. I have worked with other companies before and never have I been satisfied like I have with Works For Web. I have purchased two products so far, and plan on buying more in the future for my other website ideas."
"Absolutely brilliant - took me less than a hour to download configure and to work on the system."
