TradeFortess was warned that it is not OK to use Linode hosting back in July: https://bitcointalk.org/index.php?topic=251553.0

Migrating to a physical server could be trivial, but instead he decided to stay with Linode and ignored all warnings.

I think it's quite obvious that it was staged. Linode was chosen as a scapegoat, as previously Bitcoinica was hacked in the same way: http://bitcoin.stackexchange.com/questions/3629/what-is-the-story-behind-the-linode-problem

So this looks plausible.

If it isn't a scam, it is a criminal negligence.
