It's also different from the Scrolls situation in that Goodsmiths isn't trying to claim the right to use the Minecraft trademark. They'd clearly prefer to put the crafters in touch with Mojang and set up some license deals to make things right, rather than doing a complete takedown. But if the two sides can't reach an agreement, they've already said they're going to deactivate the listings.

The way I see it, the challenge is harmless fun with no actual legal implications. Notch should totally take them up on it.
