It should be different when it's an MMO though even if the company is Japanese. Unless you have specifically released the game to Japan only - you are catering to the whole world at that point. You would think they'd want to aswell because it can only gain them money by doing so. I hope this isn't the case and they'll prove the people that speculate this wrong because if it is true.. I don't even know. They could hire NA/EU mods because I would think SE had an office in NA/EU somewhere .. maybe? (correct me if I'm wrong here)

Also mods should quit being hidden. I hope they read this post and understand. There'll be nothing but benefits - I also hope that the mods are dedicated mods and not a programmer who does a bit of forum reading on the side. If they're getting paid to mod, they can start interacting with the community rather than being lurkers and stealth deleting threads/posts. Dealing with angry/asshole customers is part of running a business. Even if you are selling the best product in the world someone will be terrible about it and it's all about training people how to handle it correctly and ensuring you keep a customer if you can.
