I might be missing something about the timing, but If everything has been seized and shutdown on the 30th... How come OP edited his original post after the incident and announced the closure as if nothing happened (or at least that's what I imagine he edited)? also how come TRM Labs (see above post) claims that transactions were still being processed even after the shutdown on the 30th (which at the time, they didn't knew was law enforcement).
That's why I say something doesn't add up.
So the authorities let the website owner write a message informing them of the closure, on the same day they made the arrest?
I see this story being poorly told. From both sides, from the service owners' side, and from the authorities' side.
