-Wiki admins can ban users via their Preferences.
+Banned users can be configured in the setup file via the `banned_users`
+setting. This is a list of user names, or [[PageSpecs|ikiwiki/PageSpec]]
+to ban. Using a PageSpec is useful to block an IP address.
-The list of banned users is space delimited.
+For example:
+
+ banned_users => ['evilspammer', 'ip(192.168.1.1)'],
If a banned user attempts to use the ikiwiki CGI, they will receive a 403
Forbidden webpage indicating they are banned.
