Banks are always doing business with criminals and sanctioned entities and they know that, although not always when and where.

The difference is if the bank does KYC and the criminal uses a dark identity, the bank will likely get away with it. If the bank just gives each person a random number as their only identifier like the old swiss accounts, then they'll be warned sanctioned entities are using it and ultimately prosecuted when they fail to KYC (i.e. similar but but identical to CZ).

What is a dark entity? Have you worked in finance? Because if you collect KYC and accepted forged or faulty documents, the moment you figure out what's going on is the moment you call your personal lawyer.

One example is criminal pays a heroin addict for their real ID and then basically uses them as pass through nominee on the account.

Sure. If you're at a financial institution and accept that documentation, you're personally in for a world of hurt. Doesn't mean it doesn't happen, either due to someone being negligent, overworked or happy to look the other way. But if it's caught, it's not great for the individual. (The bank will survive after paying a fine unless it's systemic.)

I imagine they usually don't know. Some fraction of identities are real IDs taken advantage of by sanctioned entities. If you bank at all you knowingly accept some level of sanctioned entities, but often don't know what identity they operate.

Sure. But if the addict you mentioned's account goes from overdrafting every few weeks to holding millions of dollars, that should set off internal alarms.
