This new service from Google opens new epoch in spam protection technology.
Even if the site has no comment form (or similar) - it is still necessary to protect!
Why? Because CAPTCHA protects login form (Your site has it, right?) and doesn't allow bad guys to brute-force and use vulnerability like this: https://www.drupal.org/node/2378367
Advantages over standard CAPTCHA:
During form creation and form submission special requests will be sent to Google servers - Your server will not spend resources for creating CAPTCHA widget or recognition if this is spam or not.
This service provides advanced clever technology to recognize spam and permanently improves.
This CAPTCHA is very easy for site visitors. In half cases it is enough just to click "I'm not a robot"! :)
Advantages over others CAPTCHA modules:
Standalone module - no dependencies, no additional modules! This module provides only the needful functionality for integration and protection - nothing excess!
This module uses latest version of Google CAPTCHA V2 API.
