> Was it knowingly assisted by someone at BTC-E, or did BTC-E just act as a dumb machine?
The defendant is who run/ran BTC-E, so it's alleged to have come from the very top. The reasons why you found it so easy are probably related to why the US sees it as a criminal enterprise:
> According to the indictment, since its inception, Vinnik and others developed a customer base for BTC-e that was heavily reliant on criminals, including by not requiring users to validate their identity, obscuring and anonymizing transactions and source of funds, and by lacking any anti-money laundering processes.
It continues:
> The indictment alleges BTC-e was operated to facilitate transactions for cybercriminals worldwide and received the criminal proceeds of numerous computer intrusions and hacking incidents, ransomware scams, identity theft schemes, corrupt public officials, and narcotics distribution rings. Thus, the indictment alleges, BTC-e was used to facilitate crimes ranging from computer hacking, to fraud, identity theft, tax refund fraud schemes, public corruption, and drug trafficking. The investigation has revealed that BTC-e received more than $4 billion worth of bitcoin over the course of its operation.
