EMailcover.COM: Stop Spam: Hide Your E-Mail Address
The term CAPTCHA stands for "Completely Automated Public Turing test to tell Computers and Humans Apart."
A CAPTCHA simply hides letters and numbers in an image that computers have difficulty reading, but that humans can (usually) recognize. This site will transform your email address into a CAPTCHA-like image in order to hide it from computer bots.
I can't see any use for this for me but I thought that some of you out there might like it if you are hosting your own sites and would like another layer of defence against spammers.
Hide your email address in an image.
Emailcover.com provides this free service which hides your email address in a CAPTCHA image to help prevent spam email being sent to your email address. This dynamically created image never looks exactly the same, making it just a little harder for spam bots!
