Still. Appeal denied means a no to unban. It's your own fault, you shouldn't have hacked, threatened etc.
Can you appeal for TS banned? and @Marieke2001 You can get unbanned by contacting the staff that banned you, even if your appeal is denied.
Thought he was appealing AT teamspeak for unban at the server. But my point is still the same. He's banned for a reason why should they unban him.
