> Put simply, we allow all lawful purchases on our network.
But their "Rule 5.12.7" is... not so clear:
> A Merchant must not submit to its Acquirer, and a Customer must not submit to the Interchange System, any Transaction that is illegal, or in the sole discretion of the Corporation, may damage the goodwill of the Corporation or reflect negatively on the Marks.
Well, which one is it now? All lawful purchases (pretty clear-cut) or only lawful purchases that will not "reflect negatively" on Mastercard in Mastercard's opinion (vague as hell)?
