Why do I have to type verification numbers?

Typing the verification numbers is a security test to determine whether or not you are a human visitor to the site. Unfortunately, there are automated software robots that will crawl the internet looking for unsecure forms in an effort to submit and transmit solicitations and other spam. Fortunately, it is difficult for these spam system to read numbers from an image and it is a relatively simple task for a human. Correctly typing the numbers simply confirms that your form submission is a genuine request and not a spam submission.
