If you have too much free time, it may be worth reading the (long) "Debanking and Debunking" essay for an exploration of all of the perverse and bizarre behaviors that result from banks' fear of AML/KYC regulatory action.
My favorite example is how banks are required to file secret "suspicious activity reports" (SARs) about their customers. Even knowing about the existence of SARs can be grounds to get a SAR written against you. How's that for thoughtcrime?
