How can we see the leaderboard from last year's winterbash (2012)?
http://winterba.sh/leaderboard Seems to forward to the promos page now and not the old leaderboard.
Is there any way to get that information?
You can go to it's webpage and click the last thumbnail in the bottom. It loads a bit of the leaderboard, minus the names
It would appear that the leaderboard for 2012 is no more. It was probably because it was maintained with some sort of updating cache and then queried for current value when visited. Once the values for 2012 were no longer relevant, the leaderboard no longer functioned. From what I can tell, the location of the 2012 leaderboard was changed into a redirect to the current Winter Bash url around May of 2013.
However, you can still see all the hats and what their requirements were at archive.org :) Love that place!
