Rather than banning the user immediately, the user is given several chances. Depending on the severity of the 'inappropriate behaviour', we can issue a certain warning percentage.
Once this reaches 100%, I assume the system bans the user or the forum's admins/mods will be alerted to it.
You can read more on the warning system on the link below if you're interested:

On behalf of the admins and mods, of course we hope we never have to use this system! But it's there just in case.
