User Infractions 
The vBulletin User Infraction system is designed to automate the management of “misbehaving” users.

Infractions carry a point total that is assigned to users as infractions occur. When user infraction points reach specified numbers, the users are added to infraction groups. Infraction groups can be set up to restrict the permissions of users.
Note:
There is no method to apply infractions in the vBulletin 5 Connect Front-End at this time.
