The US doesn't give a fuck where you're based. They'll do what they want. Though in this case if the seized image was hosted on the sites own servers then this is just obviously a weak ass exit scam. Your playing with fire when you use these shady sites and most will dissappear eventually once they've collected enough funds. This is why we need some sort of decentralized hosting or options like openbazar so the police can't just take anything down they don't like the look of.
