It seems the warn was valid as you killed on suspicion, which is not valid on our servers.
HOWEVER
If you believe the admin abused his powers/ acted unfairly you can create the formal report abuse and Nepgear will handle this.
If you wish appeal you punishment, create a new post - I will use this as a demote request/ report abuse. The template and links for that are in the spoiler below:
Name - What is your in-game name?
STEAM-ID - What is your STEAM-ID?
Staff Members Name - Who warned you?
Punishment Reason - What was the reason of the punishment(s)?
Server - Which server did this occur on?
Story/Situation - What happened?
Extra Information - Anything you would find relevant to your punishments(s)?
