It may not be the hosts responsibility, but I see many hosting companies responding to this thread that they do it as courtesy to client, not because they are obligated to, but because they feel its the right thing to do by the customer. Many have said its impossible for hosts to monitor everyone's usage and keep them informed. I wouldn't say that we are all just sitting there watching the graphs constantly, but we look at patterns and get notified of unusual usage. Like Brad said, happy clients are the best clients
