This account was closed because one or more characters were identified exchanging, or contributing to the exchange of, in-game property (items or gold) for "real-world" currency. This exchange process negatively impacts the World of Warcraft game environment by detracting from the value of the in-game economy.
Even if this behavior is the result of a third party accessing the account instead of the registered user (for example, a friend, family member, or leveling service) then the account can still be held responsible for the penalty because of the impact it had on the game environment..
