You don't care? An attacker who can mine a Namecoin fork in Alice's view of split-brain world could convince Alice she's successfully claimed the name. This is particularly easy right now because very few people are mining Namecoin. Since there's so little actual Namecoin mining going on, the amount of mining power needed to take control of the network is well within the reach of a sufficiently motivated and funded attacker. -- Tony Arcieri
