Spam Prevention/Reduction - Contact Form?

Question

I want to add a simple Contact form to my web site so that customers can contact me easily.

    NAME
    

        

Answer 1

The only (client-side) way other than a CAPTCHA type user confirmation would be to write the whole thing dynamically. A lot (but not all) of robots would probably ignore the dynamic content. Eg

document.write("<"+"form>"
  +" NAME "
  +" <"+"input type='text' name='name' /> "
  +"EMAIL "
  +"<"+"input type='text' name='email' /> "
  +"MESSAGE "
  +"<"+"textarea name='message' /> "
  +"<"+"input type='submit' /> "
+"<\/form> ");
