Hello Ezeh,
After speaking with Peace Control Kyle I have come to the conclusion to deny this appeal. Although you aren't forced to refund users when they lose something to a rule you may or may not have broken, you still made the silly decision to put an instant kill wall in a public area.
You also ignored Kyle when he asked you to at least put the forcefield into passive mode so future incidents didn't occur, so I think it's fair we ignore your request to have the punishment removed.
