It's not targetted by pressure groups at the moment. MasterCard isn't acting out of its own moral convictions here, so don't expect these rules to be enforced wherever they might apply.

Oh please. As if Mastercard is beholden to some grass roots movement from Australia.

...So their quote "we require merchants to have appropriate controls to ensure Mastercard cards cannot be used for unlawful purchases, including illegal adult content." is just a lie?

I mean yes, of course they're lying? the article quotes the actual rule here, which is "don't do anything that might make us look bad".
