Staff is prohibited to view your content.
The staff does not have access to your content. Access to your content is controled on a need-to-know basis and is therefore restricted to those who need access in order to facilitate your account or your questions. For example, a member of the support staff may have to access your account in order to answer a question you have posed, or a member of the billing staff may need to access your account to clear up a billing question.
Employees are vetted through background checks and sign non-disclosure and confidentiality agreements. Violation of these agreements will lead to disciplinary action, up to and including possible termination of employment.
