Is there any way to use some kind of captcha when we use the facebook comments app?
I had in my site the FB comments feature (integrated with a SMF forum) so every comment gets posted in the forum also, but this is like give the spammers a free candy...
Any Ideas on how to put a captcha of some kind for the fb comments?
pd: If needed my site www.desadaptados.net (sorry is a spanish based site)
The comments plugin does not have a captcha option. So, what you will need to do is to not display the comments plugin until the viewer of the page to enters a captcha. Once the captcha is correctly identified, then you can add the comments plugin to the DOM and can be parsed by FB.XFBML.parse() to get it to be rendered.
