Spam form submissions are form submissions that contain unwanted or harmful information. Occasionally, human users try to flood forms with undesired results; however, spam submissions are usually generated by bots crawling websites and automatically submitting your forms.
How CAPTCHA protects your forms
By default, all forms use Google reCAPTCHA (version 3) to protect them against bot submissions.
reCAPTCHA uses risk analysis engine that adapts its challenges to stop bot software from taking part in abusive activities, while allowing legitimate users to submit responses without interruption.
For example, competition forms are often the target of bots that spam repeated submissions. CAPTCHA helps prevent this without adding friction for real users.
