Pretty simple if you have a player and cant keep track of appeals/warnings.

Let's start off in PointsHandler:

/*
 * Warning Points
 */
private int warningPoints;

	public void setwarningPoints(int points, boolean add) {
		if(add)
			this.warningPoints += points;
		else
			this.warningPoints = points;
	}
	public int getWarningPoints() {
		return this.warningPoints;
	}
	public void incrementWarningPoints() {
		this.warningPoints++;
	}
	public void incrementWarningPoints(int amt) {
		this.warningPoints += amt;
	}
	public void setWarningPoints(int warningPoints) {
		this.warningPoints = warningPoints;
	}

Now we if they have more than 0 warning points they will get a notification on login.

PlayerHandler: (Under get minutes bonus XP method)

        if(player.getPointsHandler().getWarningPoints() == 10) {
        	World.deregister(player);
        	String p = player.getUsername().toLowerCase();
        	PlayerPunishment.autoban(p);
        }
        if (player.getPointsHandler().getWarningPoints() != 0) {
        player.getPA().sendMessage("@red@[AUTO-BAN] If you reach 10 Warning Points you will be Auto Banned.");
        player.getPA().sendMessage("@red@[AUTO-BAN] You currently have "+player.getPointsHandler().getWarningPoints()+" Warning Points.");
        }

Next we head to playerpunishment.

	public static void autoban(String player) {
		player = Misc.formatPlayerName(player.toLowerCase());
		if(!AccountsBanned.contains(player)) {
			addToFile(""+BAN_DIRECTORY+"Bans.txt", player);
			AccountsBanned.add(player);
		}
	}

Finally the command: (CommandPacketListener)

	if(command[0].contains("warn")) {
		String plr = wholeCommand.substring(5);
		Player playr2 = World.getPlayerByName(plr);
		if(playr2 != null) {
			playr2.getPointsHandler().setwarningPoints(1, true);
			playr2.getPA().sendMessage("@red@You have received 1 warning point!");
			playr2.getPointsHandler().refreshPanel();
			} else
			player.getPacketSender().sendMessage("Could not find player: "+plr);
	}

I left a bracket out, if you can't figure it out you probably shouldn't be reading this.

I like it, thanks
