After being DDoSed?  Like practically every other Bitcoin site at some point?  Are you fucking retarded?  How does being the victim of a DDoS say anything at all about their trustworthiness?

As for other criticisms, such as the shitware they're running, those points are valid.  But there's no level of "security" that is going to get around a high volume DDoS, and if you think otherwise, you're a fucking idiot.  Bank service sites have been taken down by DDoS for days at a time.  Do you think they're not paying top dollar for the best security they can get?
