My understanding is that in most cases of fraud, what customers are looking for (clear explanations for why the account was suspended, funds are being held, etc.) will simply not be possible, either due to legality, or that the company will intentionally withhold information so that the fraudsters won't figure out how to work around the protections. Obviously this hurts legitimate customers who get tripped up by the system, but at Stripe's scale that's probably the "price of doing business" as the saying goes.
It's true that we can't be more specific about users in HN posts. But we do hear the legitimate feedback about getting more specific/helpful in sharing status with users where we've asked for more info from them (or when they are asking for more info/help from us). I don't think we've found the right balance in either case yet -- working on it.
