- In the Spam protection section, you can check to enable or uncheck to disable Google reCAPTCHA for that location:
Can I hide protected by reCAPTCHA?
Avoid using the display: none; CSS property to hide the reCAPTCHA logo. Do not use the “display: none;” property to hide the reCAPTCHA logo (badge) because it will completely disable your spam protection. You must use either “visibility: hidden;” or “opacity: 0;” to keep your spam protection working.
