I investigate these PPP Fraud cases within Financial Crimes Investigations. I can assure you they have no way of even sorting out who has received them, and that there are actual, real deal criminals getting huge EID loans and grants, half the time in their own name or someone else's, into their own personal accounts while they have no businesses with us or elsewhere.
We are only catching them incidentally from a random branch teller noticing it and reporting it, or say if there's related activity that would be caught by a monitoring algorithm (ie withdrawing the full grant in cash causing a spike in the pattern). There is no verification whatsoever happening on our end, and they do not seem to have any ongoing ability to find the credits.
It's an unmitigated disaster. I'm not even a fraud investigator, I'm in AML-that's how unable they are to deal with it.
And the kicker? We're not even kicking these people out. They're all still customers. So to answer your question I really would not worry lol
