I do not know anyone named Josh, but that Inaba guy probably has more to worry about from the Feds considering many of his posts about "hosting money printing machines so you can avoid paying taxes in your homeland" sound like federal crimes that the USA is not amused about anymore.   
The DPR case clearly stated that federal agents have be on bitcointalk since 2011, monitoring, engaging and building cases.   I find it hard to believe that they will ignore this Inaba's posts as he made himself such a focus by acting the ass constantly.
