How's this for a bad idea: a company wants to send robots to the moon to draw gigantic ads on its surface. Ads so large you could see them from Earth. Yes, gigantic ads on the moon.
Thankfully, there's no way the company will be able to get enough money to get their project off the ground. And if they somehow did, the outcry against their plans would be deafening. Nobody has the right to vandalize the surface of the moon; it takes some serious gall to think otherwise.
