It may sound silly, but it can really cut down on useless emails.

Computers are good at a lot of things, but they stink at certain things that the human brain excels at. Creating an image and asking a person to determine what letters are in the image is a good way to determine if a person, rather than a computer bot, is filling out a form or attempting to send a message. This system of validation is called CAPTCHA and is a type of test to prove you are human, known as Reverse Turing Tests.

If you use forms on your website to collect information, Spam bots will flood you with useless penis enlargement ads and other pornography. Using CAPTCHA is an effective way to foil spam bots since bots cannot verify the letters in an image.

BlotPoint can implement CAPTCHA on your site. For an example of what a CAPTCHA is, visit our contacts page.
