It only resets when someone pushes it. It's been getting closer and closer to 0 as the days go by since it started. There are also bots waiting for it to get low so they can snag a low number.
Is there any code available to prove that?
Network monitoring on the browser shows nothing (maybe an anti-debugging technique)
tcpdump shows an SSL connection to EC2
You really can't synchronise so many people (especially with connection latencies), I think there's some amount of faking in it.
