Since the staff member that banned you is no longer a part of the staff team, I will be doing this outcome myself.
After looking over your appeal and personally witnessing your behavior and attitude when you were playing on server I have come to a conclusion.
Simply due to the lack of apologetic behavior and the lack of playtime on other servers, this shows how you are unwilling to show us your change until its too late, and are not even sorry for your behavior or attitude.
I recommend being more apologetic in future appeals and by playing and showing change on servers before you appeal instead of the promise of change after.
Consider this appeal:

Have a nice day.
