But really what he did and what his intentions seem to be fits almost perfectly as digital vandalism against Ripple.
Except that the actual vandalism/damage to the Ripple system was
non-existant. If someone cons a bunch of newbs into publishing their bitcoin secret keys that doesn't damage bitcoin or cryptography or prove any big flaw in either; it just shows newbs (and others) are gullible and can be conned. The only real damage (beyond those conned) is the misinformation. He (and others) are just using this as an excuse to spread more misinformation like this statement:
Even if you have never trusted me, your Bitstamp IOUs could be being substituted for my IOUs.
Which is completely and utterly false. Ripple only gives you balances from people you directly trust. He's either purposely lying/exaggerating or he completely doesn't understand Ripple.
