Why is it called Ghost Captcha? Because like a ghost, it is an invisible force, working quietly in the background to detect and block potential spambots. Yes, Ghost Captcha does come with its own standard captcha tests, but these are only displayed as a last resort, after suspicious browsing activity is detected.
Why display captcha tests only as a last resort? Because captcha tests are annoying. They treat all users as suspects, who must prove they are human before logging in or posting anything. Many are hard to fill and inaccessible, especially for those with eye problems and other disabilities. No wonder Code canyon and other Envato sites just recently removed all to captcha tests, a big relief to all its genuine users like you and me.
So, how then do you keep your site secure from spambots and other malicious programs out there without captcha always displaying captcha tests? Use Ghost Captcha, which works by monitoring a users behavior to separate the humans from the bots. It uses a mix of the honeypot technique (https://en.wikipedia.org/wiki/Honeypot_%28computing%29')and time monitoring to separate the humans from the bots. All this is done quietly in the background and if any suspicious activity is detected, Ghost Captcha then loads a normal captcha test. Using this technique, most of your genuine users will rarely ever need to see or solve a captcha test.With Ghost Captcha, you no longer have to choose between blocking spammers and annoying your genuine users.
