When you get a message saying you have recieved a warning that means that you have a warning watch placed on you. What this just means is that you have violated a rule and are under monitering for an amount of time to make sure you don't do it again. It is usually the person who saw you break the rule who dose the montering. If you do break the rule again though then you will be set to the next line of punishment stated under that rule in crime and punishment.
