I can't imagine that the contact form can automatically collect Google and Facebook information from website visitors, but perhaps the moderators and the other users know more.

Or is something else meant?

Hi, it may require some sort of plug-in or integration but I am confident that it is possible. The idea being to make the data entry more seamless. 

Hello Francos

Unfortunately, the software just doesn't offer such functionality out-of-the-box.

The only way to get something like this done would be through the addition of custom codes targeted at this result specifically. However, the official Staff cannot provide support for the creation or implementation of such codes. However, the software has been fitted with several areas where to insert custom codes, so should you be able to produce these yourself or get them done for you, you will be able to incorporate the codes into the projects

I remain available here
