It works tirelessly, day and night, applying various checks to each comment that comes in and giving it a spam score – any score too high and the comment goes straight to the spam bucket in disgrace. No third-party registration No JavaScript required Best of all, no captchas There are no visible changes to your website and you don’t need to set anything up – just install, activate and go!
