Quoting above from another thread. Could this have been going almost a week (nov 30th was above post)? This augur dev guy has 100,000 rep on polo and wasn't able to secure his polo account for a week? Must be more to this story.
Exchanges commonly say they've been hacked and all the coins were stolen. There's always speculation it was an inside job like with cryptsy. Although there will be speculation the augur dev guy is behind it, without proof it will only be speculation. It's suspicious that a dev would put so many coins on polo. If he was planning to dump them he can't have much faith in his coin, or did he put them on polo so they could get 'stolen'?
Its called the I got hacked retirement plan.
