How to use silentCAPTCHA AntiBot system to detect SPAM Bots
silentCAPTCHA AntiBot system is ShieldPRO's exclusive bot-detection technology that removes the needs for CAPTCHA and other challenges.
This feature is designed to replace the CAPTCHA and Bot Protection options. It distinguishes bad bots from all your other “good” traffic (humans + good bots).
All visitors who try to post a comment get a “ bot reputation score” and if they make a request that falls below the score, the request will be rejected.
How to enable this option and know if it works
This option can be found under the Shield main navigation menu > Security Zones > SPAM > click Configure (gear icon) next to Block Bot Comment SPAM component. Then, select Bot SPAM tab and enable Block Bot SPAM option.
The bot will trigger the Shield's offense and the all activities can be seen in your WP Activity Log.
