Alternative to Captchas (Without Human Interaction)
This security field is based on the perception that spambots post data to forms in very short or very long regular intervals of time, where it takes reasonable time to fill in a form and to submit it for human beings. Instead of captcha images or Ajax-based security interaction, the SecurityField checks the time of rendering the form, and the time when it was submitted. If the interval is within the specific range (for example, from 5 seconds till 1 hour), then the submitter is considered as a human being. Otherwise the form doesn't validate. Usage example: class TestForm(forms.Form): prevent_spam = SecurityField() # ... other fields ... The concept works only for unbounded forms.
