Entering out of bounds area.
Many people entered before and didn't get banned, I entered shortly after because I was curious and got ip banned. Command blocks can't even be edited in survival mode, so no harm was possible.
You used a glitch to enter an off limits area. Irrespective of your intentions if we wished you to have access to these areas we would let you. Anyone found in any such area will be banned immediately.
Your ban stands, best of luck elsewhere.
