Just curious:
I checked my behaviour on upvoting / downvoting; the rate is almost 30:1, which means I am not much of a downvoter. A few days ago however one of these rare occasions took place, and I was prepared to be "knocked out" by the loss of no less than 1 point reputation.
However, up to now, it has not had any effect; my reputation still ends with 8 or 3, would have been 7 or 2 now.
Is this an error in the system or is there another reason?
