@hidetada: Unfortunatelly WG said it pretty straight forward. They are not going to tell you for what mods you got banned. They do not need to and are not obligated to. It might compromise their "detection methods", so they won't do it and stated so in their Fair Play Policy post. Only information given to you will be that you're banned for certain reason, like using fobidden mods, nothing more. Quite re-assuring right ? :-)
