Upgrade: Captchas

When we started our service we added Image Validation to public forms (Contact Us/User Registration/etc) to ensure a human was filling them out. This was done to prevent SPAMmers from utilizing these forms.

Occasionally we will receive reports that the Image shown does not match the Validation required to complete these forms. These issues are 99% of the time attributed to cache settings on a member’s computer or some proxy server in between. Basically an old image is shown vs. one the system expects – thus the form cannot be completed.

We have updated this component of the system two times in an effort to force browsers to load a new image every time. Unfortunately we cannot seem to get 100% of the browser cases covered.

Thus, we have switch from Image Validation to Math Text Validation. This will remove the potential for cached images and will ensure 100% of the validations.
