Warning Message: Shield Security Bot Check Failed

When you use the silentCAPTCHA AntiBot system, you may have get the following warning message when you try to login:

The silentCAPTCHA is tracking each IP address and the actions they take on the site. If a visitor or user is triggering Shield defenses too often, eventually they'll reduce their reputation and eventually Shield will see them as a bot.

Your first step when you can't login is to use a forceoff method. This will keep plugin active allowing you to get back into your site and once you are in, check your WP Activity Log. 

If you look at your WP Activity Log and filter for your IP address, you'll see notification for why your IP was prevented from logging-in. It'll say your bot score was too low and didn't meet the minimum reputation score.

Example

When the silentCAPTCHA is in place, visitors get a "bot score" and if they make a request that falls below the score, the request will be rejected. Shield creates a "bot score" by using over 20 different signals to build a bot score for each IP address, including our unique "Not-Bot" system.

The all details can be found under the IP Analysis section. For example:

General Info

Bot Signals, including a total reputation score

So this will help you to understand what this particular IP address (visitor) is trying to do and what Shield offenses were triggered.
