This is a maintenance category, used for maintenance of the Wikipedia project. It is not part of the encyclopedia and contains non-article pages, or groups articles by status rather than subject. Do not include this category in content categories. This is a tracking category. It builds and maintains a list of pages primarily for the sake of the list itself. They are not part of the encyclopedia's categorization scheme. This category is hidden on its member pages—unless the corresponding user preference (Appearance → Show hidden categories) is set. These categories can be used to track, build and organize lists of pages needing "attention en masse" (for example, pages using deprecated syntax), or that may need to be edited at someone's earliest convenience. These categories also serve to aggregate members of several lists or sub-categories into a larger, more efficient list (discriminated by classifications).

This is a non-diffusing subcategory of Category:Banned Wikipedia users. It includes users that can also be found in the parent category, or in diffusing subcategories of the parent.

This category is for accounts that have been banned by decision of the Arbitration Committee. It is an incomplete listing of such accounts, and it is not necessary to seek out and tag user pages that may be missing this category. If there is a reason to add a specific user, notifying an arbitrator or arbitration clerk would be appreciated.

This category is added by the {{banned user}} template when the parameter {{{by}}} is set to "the Arbitration Committee". Please note that the template will not produce a banner on the user page; this is intentional.
