When users are either banned, or assigned Warning Points, do these events get logged at all? In quickly looking at the available logs, they don't appear to be but in my opinion, they should. I've had an occasion where a user claims to have been banned, but there is no record showing it (is there?) One possibility is that a Moderator momentarily assigned him enough Warning Points to trigger a time-based ban, and then deleted those Warning Points. The end result is that the user remains banned, but there is no evidence left behind -- no log entries, no historical warning point entries on the User's profile page, nothing -- to explain the ban.
