Hello,
regarding censoring system, we are working on better version of it and it shouldn't censor random words but only banned words or phrases.
About your question why is not your character name allowed - we don't feel like it is appropriate to use this kind of name. We are offering a nice deal to you, free rename card so you can change your character name for free. Take this as first warning, if you won't change your character name, we will do it manually but we won't offer rename card next time.
About bad translations for Ninja test - we are already working on improved version and it will be added later this week.
Have a nice day.
