MediaWiki:Usernameblacklist

From Meta, a Wikimedia project coordination wiki

Administrators: Be extremely careful regarding the entries you place on this list. Simple typographical errors can block the creation of thousands of unintended usernames. Don't add a term unless you are completely sure it will not affect innocent users. For example, "EmbarassedMonkey" because it matches "ass". This is the w:Scunthorpe Problem. See here for general information about w:regexes (which are used here).
