Data Privacy

Dear Support Team,

is there something like a report to check if all registrered user clicked the data privacy hook?
I know that normaly nobody can`t register without clicking the radio button of the data privacy (http://www.maintal-marktplatz.de/zum-social-room/login.html).

But on my site the new person who wants to be a user can also register on this site: http://www.maintal-marktplatz.de/anmelden.html
Unfortunately, there is no radio button for the privacy policy.

But if the new person register though the mentioned site he can also use the EasySocial tool. But then without hooking the data privacy box.

Do you have an idea how I can check this user without the data privacy or do you have an idea how to handle this unpleasant thing?

Thanks in Advance
Jannis
