I am wondering how many people will actually fill in the form with their real information not even thinking 
It's fine, the data is only locally submitted:
Yours to verify with your preferred browser e.g F11 (Chrome) , F12 (Firefox) , installing firebug etc.
And besides, is there really someone here who will give their credit card details? That's a dumb move. Even on KYC policies of crypto exchanges at most of the cases, credit card details isn't even mentioned. Make sense.
