This page in a nutshell: Treatment of an editor must be based on the behavior of the editor, without any regard to the editor's status.
On the English Wikipedia project, all users, from the IP user to the most senior of admins, are afforded the benefit and respect of our fundamental policies of governance. All users should be accountable to these policies and guidelines, and no users should ever be exempt from them. Policies apply equally to registered or non-registered users, regular or occasional editors, administrators and bureaucrats regardless of tenure, and regardless of 'rank'. Should a situation ever arise where the question comes up: "Is this user exempt from the community-established and accepted policy in question?" the answer will be simply, "No."
