Another solution is to smash that device with a hammer. Repeatedly. Don't stop before you are sure it is destroyed. Then it has no MAC address. Later, if you search the world, you won't find it's MAC address. Eventually through exhaustive search you might be able to make a good guess as to what the MAC address was. Did that help?
