The asset freecing is one thing, but trying to prosecute a company without an US address under US criminal law is much more troubling. If I have a personal blog, should it be possible to hold me accountable according to the criminal laws of every single country in the world? Obviously not, how could I possibly comply?

Now an internet company with customers around the world is different - but not so different that this should be possible under criminal law without a very clear pre-written law.
