This is why absolute anonymous crypto-currencies will never catch on. Too much trust must be put into the hands of the developers. How do we know this vurnerability (and maybe others yet to be discovered) were not exploited for months? They didn't even share the methodology and tools they used to check the blockchain for this particular exploit. I can understand their assurance that everything is fine, because otherwise any coin on this list gets basically useless overnight, but that's not how it should be handled.
