Denied, since i dont see any admin nor server rule break (no discrimination/racism or excessive insult). Even though, I expected admins to behave better than that, which was also the reason players were not allowed to use /ignore cmd against admins. I've decided to update /ignore cmd to allow players to ignore admin now. The admin may use /say cmd to bypass it when necessary; insults are obviously not part of it.
Notes:
1. For players: You can use /ignore cmd if you cant stand other player's behavior (including admin)
2. For admins: You can shun player if their behavior is out of control/keep provoking admins (as stated in server rules).
