Would anyone mind clarifying and stating the rules in regards to clan banks and account sharing? Our clan bank was permanently banned for seemingly arbitrary or perhaps personal reasons rather than any defined rules.

According to the staff member that banned the reasoning was a statement along the lines of "it was used for dueling, betting and playing in clan league on top of being a clan bank therefore I will ban it forever without warning".

I'd appreciate if these rules were clarified as to prevent people from getting their clan bank accounts banned in the future due to these unstated rules, thankyou.
