You can literally get your acc banned/disabled with no changes visible on profile.
You can still have sig, ava, notes, 10% warn and permanent ban while user is still Group: MEMBER instead Group: BANNED
So in theory there's no way to say if someone stopped using JSP or got banned for some reason
So you really have no idea then. No reason to think they're disabled?
Also you keep saying banned when we're talking about disabled.
