Scores in the negative are kept track of despite not being displayed, however. In particular, people with negative karma have a commenting frequency limit, whereas people with zero karma do not.
Scores for total karma are displayed as zero if they are negative. Scores for individual articles can be negative (and in fact it is back to −1). I have various hypotheses about why the score has moved up but I’m waiting to gather more evidence before I state them.
As far as I know, the minimum possible karma is zero; scores below that are, IIRC, displayed as zero.
