You can add a confirmation 'I'm not a robot' (CAPTCHA) in any of your registration or order forms. This feature will reduce the number of spam registrations. CAPTCHA will help to understand who the user is - a person or a program. If the user cannot pass the test, then he is likely a computer and cannot send the form.
This feature will inevitably reduce conversion - we do not recommend adding it to your forms unnecessarily. The use of captcha is recommended only when receiving massive spam registrations in your account
To enable this feature, you need to add the 'CAPTCHA' user fieldin the 'Form' block.
The added field will be displayed on the published page as an additional field for confirmation 'I'm not a robot'.
Without the confirmation, the form cannot be sent.
CAPTCHA reduces the likelihood of spam registrations made with the use of robots.
However, it does not protect against false registrations made by people - people can pass the CAPTCHA test. Some bots are also able to pass the CAPTCHA test and register. CAPTCHA does not guarantee 100% protection against spam registrations - it only makes the attack more difficult and more expensive for an attacker.
