Hi, is there a way to stop/prevent parents from taking bank loan?

My parents keep taking bank loan/credit card debt to join some illegal investment, and still think one day they can get back profit but now banks already calling in non-stop, and they cannot repay anymore.

I worry they might not even consider to go AKPK because they keep believe that soon enough the illegal investment thing will give them back the money then that time they can repay debts.

So I wonder is there any way to ban them from bank loan?

Well that's one of the way for sure

Maybe I should put in the point that, I'm considering to help repay the debt but I want to make sure they don't do it again.
