The current 'Stardockia-wide' karma list plus the disappearing karma problem make me suspect that Bara is in the process of making karma totals consistent across all Stardock forums, even if you've never made a post at that forum directly. Or else putting a filter on the report page to exclude 'non-local' sites is a low-pri task.
@the OP: That earlier chocolate-as-crank line is one part of it; karma can mean nothing when you have none, but if somehow folks pile some on you and then you 'act the same' but go for a while without more karma, you think about karma and get irritated by confronting your own vanity. Also, I think the Elemental devs once used karma as one criterion for choosing a select group of beta volunteers for some NDA-covered testing.
