This category is for accounts that have beenbanned by decision of theArbitration 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 anarbitrator orarbitration 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 willnot produce a banner on the user page; this is intentional.
