Why is this neccessary?
This is a CAPTCHA test to prevent spammers and automated spammer programs from sending us email.
A CAPTCHA (Completely Automated Public Turing Test to tell Computers and Humans Apart) is a challenge-response system test designed to differentiate humans from automated programs. A CAPTCHA differentiates between human and computers, bots and spammers by setting some task that is easy for most humans to perform but is more difficult and time-consuming for current bots to complete.
Frequently, a CAPTCHA features an image file of slightly distorted image. A human can usually read the characters in the image without too much difficulty. A bot program is able to recognize that the content contains an image, but it has no idea what the image is.
