Borrowing money from loan sharks is the worst thing you can do. And in China, they have a different way of making sure they can collect the debt. Internet loan sharks in China are now
demanding nudes from female college students who are seeking out a loan.
The lenders require females tosend nudes of themselves along with copies of their ID cards. The photos will be made public if they are late on payments.
It may be seen as collateral, but this is straight up blackmail.
Probably best not to borrow from loan sharks, regardless of whatever collateral they need.
