But why they asked anyway that kind of things like parents names,date of marriage,date of birth.place of marriage?
Is this comes by some law or just website asked that information and who wanted to be an adult models,they just gave information,what asked.

My guess is so they can cover their ass if someone underage presented fake information. They probably used some background checking service to make sure there wasn't any misaligned information.

Still a huge leak. I'd never give a company access to my passport info and such. Hell I didn't even tell the hospital where I worked, any background info, income, etc when my child was born. It wasn't under my insurance so they didn't need to know any of that. Companies ask for too much information because people willingly hand it over. Then a large DB leak like this happens and everyone is in shock and awe.
