Banks have algorithms that can detect when a customer is going through a serious financial difficulty and may become a liability.

I know because it happened to me.

The fact that you became homeless, no food for one week, couldn't graduate because you couldn't pay tuition etc. all point to the same thing. BTW, colleges don't screw you over if you are late paying tuition for just one week. I know that quite well too.

When my bank closed my accounts, I was super annoyed. But I knew why they did it.
