The list of weak passwords correctly excludes Credit Card PINs, but doesn't exclude the PIN field available to items in the Bank Account category (which can also be set, presumably for things like cash cards). Not much you can do about a PIN, as they will always be terrible by any password metric -- any chance of excluding that field for the Bank Account category in the same way as it is already done for the Credit Card category?
