uhhh it's been a while but yeah it's true that people who are banned at least on the forums (used to?) get a reason. in-game not so much. causes a lot of confusion in my observation.
not sure if there is really a way to give reasons for bans in-game? idk though, someone may conform this later.
leaving out a lot of detail here because i'm afraid of making your threat subject for closing, but i hope this makes sense.
