People can be banned in VSys, that is, marked as undesirable and never allowed to participate. In order to track why someone was marked as banned, VSys lets you define any number of reasons and have those available in the profile editor. Set up banned reasons by clicking on Banned reasons on the Setup panel. Use the Add banned reason link to define a new reason, or on an existing one to edit or delete that reason.
Deleting a banned reason removes that reason from all people who currently have it, but does not un-ban the person.
