As has been said, nothing was sent.

It was likely  51%-attacks. Most likely, the exchanges were the victims, too.

For the PAC network, the exchanges are simply another wallet clients having a lot transactions which have to be sorted out by them, including preventing the attackers from spending or running away with the "double-spent" PAC's. That's why the exchange had to put the wallets under maintenance. The exchanges with less PAC transactions should have had emerged from the maintenance mode sooner. A lot of works had to be done @every exchange. In the end, someone still has to cover the shortfall. Therefore, a lot of accusations to any entities are completely unfounded.  

Looking forward to new PAC thread.

The party is just beginning.
