I suppose the big question is can anyone confirm that our private mail is never read unless a concern has been raised?

 If a concern is raised is the member notified that their mail is going to be read?

How much evidence is needed before someone reads the mail?

 Are we sure that no-one gets the urge just to peak at someone's mail?

For example if someone accused me of spamming through the IM what evidence would you require before you read my mail?
