From my understanding, they don't like how westerners act. More so Americans. Americans can be very racist and were. They insulted the jp player base when they got a chance to. Like the NA laught at the jp's wanting other to ask b4 checking since their check message was a tad on the >.> "the fraq why you peeping at me". I never had an issue with the jp player base. I partied with them and try to respected how they were. They prob dislike when we use auto translation to say dirty stuff and I don't blame them.
