Spammers can use automated tools to post many unwanted messages very quickly. To protect a website from their attacks, WorksForWeb added CAPTCHA in all their classifieds scripts including Auto Classified Software.
CAPTCHA is a Completely Automated Public Turing test used to ensure that the response is not generated by a computer. Humans can easily pass this test but computers will hopefully fail.
A captcha includes a picture with the distorted and rotated text.
Currently, the captcha is implemented on Contact Us, Contact Seller, Tell Friend, Contact User, and Registration pages. For all these pages the admin can easily turn it on or off.
"...I am still look at my website and it is very very good looking website and I am so much happy and I appreciate all your work ... Thank You,"
"Customization team is SUPER GREAT to work with."
"Just wanted to tell you that you're doing great job! I'm not a buyer, but thank you for what you are creating!"
