I think it would be reasonable to ask you, and other supporters of this, to provide emperical data of the positive law-enforcement impact that grepping transactions for "ALEP" has had, so we can weight it against the human cost (capital and time spent across all sides, including legal departments in financial institutions, Google Docs written, impact on affected customers).

Because the default assumption of a normal person is, of course, that this is ridiculous.
