Discipline
Discipline tools help you manage problematic behavior and maintain a healthy community environment through warnings, discouragement, and bans.
Warnings
Warnings allow you and your moderators to add warning points to users when they violate rules. These points can then be connected to actions that apply restrictions or bans based on how many warning points the user has.
Banning users
As a final resort for most disciplinary situations, you can temporarily or permanently ban a user from your site. A banned user will receive an error message on each page of your XenForo forum, indicating that they are banned and, if relevant, details about when the ban will be lifted and the reason for the ban.
Discouragement
At times, banning a person may not be entirely effective. With the design of browsers, it's easy for a problematic user to register a new account.
