  <body>
    <form action="?" method="POST">

Analysing Captcha Notifications

You should not be 100% reliant on CAPTCHA. Each notification you get should be analysed once for security. There can be failures produced by even real customers and reaching out directly would be a good option in that case.

If the amount of failures involving real customers rises, you should change the CAPTCHA approach by using methods like shortening the code, enlarging the window or removing Captcha from unimportant pages.

Failures that occur from unknown areas should give you pause. An increase in CAPTCHA failures is a sign that your website is a target. Increase your security protocols for your own safety.
