Why would they ban ONLY US players for some US players hacking? Do other nation's not hack either? That just seems like stupid logic to me.
English=/=American and I'm saying IP ban as in banning IP outside of Japan because for one, they do not support players outside of Japan, languages outside of Japan and from the look of things, there is going to be an English release one day and hence they want people to stick to the proper servers and supported areas for the game. It's also not going to be because of all the English hackers but also because they know our massive group is only going to have a few people putting in cash especially since no one can understand anything and they beefed up encoding to make sure you can't translate the game for a reason.
