Exactly.

Just like they repeatedly say "we don't sell your data!" they will come up with their own meanings of words and phrases to try to pacify people.

Probably not directly, but I can't imagine what purpose this would be except to sell ads. That's what Facebook's business is all about.

I wouldn't be surprised if they were trying to run some sort of regression of behavior against bank balance and debt load. So sure, they're not using your bank account for ads, just a proxy of your bank account for ads.

Finding proxies for income is decades old (zip code and magazine subscriptions being the classic example), but I'm not aware of anyone doing at this scale and with direct input from banks as opposed to volunteered information.

And their CEO will write a blog post about how they are "asking themselves hard questions." Followed by an FB advertising campaign stating "financial fraud is not your friend."
