Just because you have a moral problem with the customer doesn't mean they are a malicious user. Even if a user's actions are outright illegal, illegal is neither sufficient nor necessary for saying something is wrong in the moral views of anyone who uses a moral system divorced from the legal system. In short, deeply held moral views can differ so greatly that a common language to describe the situation can be impossible unless one sticks purely to the facts which include accepting the legal system does exist and make judgment calls but putting no authority in those calls.
