Your ban is set as 15 days, reason was "no singing". Singing songs over the mic is not appreciated. I warned you after your first round of singing to stop, and you continue a few minutes later. Whatever status you believe you hold here does not make you exempt from the rules which can be found at

Your ban, like all banned players is available for appeal and discussion here and in the admin forums. As far as I am concerned you will serve the time given
