Whats so wrong with with wanting to talk to your friends if you speak japanese? My jp friend can speak english very well and can switch between both easily, google translate does not come close to translating a conversation in japanese and is not feasable for fast replies.

This game has been out for a long time and despite the jp only crowd there have been some amazing freindships between jp and na players, some people have learned japanese just for that reason, no need to bedgrudge them the gift of conversation with a friend.

Unless you're botting or hacking SE is not going to suspend you for windower.
