I have two upvotes on my answer on question: http://stackoverflow.com/questions/1489474/how-to-test-ecommerce-software-for-credit-cards/1489666#1489666
But I got 5 points for them.
I am not complaining about the points. I am curious how I got five points (it was initially 5 for the first upvote, zero for the second).
I have 130 rep points for today so I am not near the cap.
It isn't a community wiki question, but regardless, I didn't think it was possible to get 5 points.
