I recently discovered this project and it looks very interesting. I understand why broadly distributed data is effectively protected against censorship, DDoS attacks, since there is no single point of failure and anyone can pin and redistribute it. However, it also seems that it takes some time to propagate any new information. So the question is, if the attacker targets the publisher by its identity, wouldn't it be much easier to "silence" the data which hasn't been propagated yet? And what are possible counter-measures if this is ever an issue?
