XenForo provides extensive tools and utilities to drive engagement, reward participation and handle misbehaviour.
At the core of the XenForo user management system is the concept of permissions: user rights to perform actions and view content.
Users may belong to multiple user-groups, with permissions attached to each group or to individual specific users.
A user's final materialized permissions are calculated from their combined user group permissions and any permissions set specifically for that user.
Customize the data you collect
In addition to email address and other essential data, XenForo makes it easy for administrators to create custom user data fields to store information such as a Twitter handle, favorite color, location etc.
Custom field values can be freeform, of a specified format or selected from a predefined list, with styling set up by the community administrators.
The trophy system in XenForo allows site owners to award their users with 'trophies' for reaching specific milestones, such as posting their first new thread, receiving their first positive reaction or on the anniversary of their membership.
Trophies can be defined for a huge variety of criteria or combination of criteria, and each trophy adds a number of 'trophy points' to the receiving user's profile, which can then be used to trigger further actions or rewards, such as an upgrade to the user's 'title'.
Custom user lists
Rather than a simple list of all the registered members of your site, instead XenForo offers the ability to define custom 'member statistics'.
These allow you to list those members with the most messages, the most positive reactions, members with birthdays today or any number of other metrics you may wish to employ.
Content posted to a XenForo installation can be reported to staff by other users and will appear in the staff console for their attention.
Staff may issue a formal warning to a user, along with an explanatory message.
Warnings can act cumulatively, so the most recent warning may trigger an automated sanction against the offending user such as a temporary suspension of privileges or even an outright ban - all without the staff having to keep a manual log of trouble-makers.
When users misbehave persistently, staff may prevent them from interacting with the community by banning their account, either permanently or for a specified period.
The nuclear option
For those visitors who won't take the hint, 'The Discourager' is a system designed to frustrate troublesome users to the point that they go away of their own accord.
You can define a random chance of receiving a blank page, or of a page taking an excessively long time to load, or of receiving a server error etc., such that the targeted user may presume that your site is having server or connection issues and leave you alone, instead of fighting through the interminable errors to spread their mischief.
