Could Integrate the function of recaptcha in the JFBConnect

JFBConnect does function with Joomla's built-in Captcha. There's a few ways to make it work:
* Disable JFBConnect's Automatic Registration flow. In our mini-registration flow, the captcha you have configured in the Joomla Global Configuration area should show and work.
* Enable the Social Profiles - Joomla plugin and set the "Registration Component" option in JFBConnect to "Joomla". That will take the user through the standard Joomla registration flow where the Captcha should work.

If you can describe when captcha isn't working (your settings, problems you're encountering, etc), we'll gladly help investigate further.

Thanks,
Alex
