Thank you for sharing. I had almost forgotten all about this case.
I'd love to see the actual evidence in regards to the "Locky" allegations. I recall WizSec speculating that BTCe was probably in the business of laundering funds for various hackers, and not necessarily behind the hacks themselves. With Locky, I can't find anything more than this linking Vinnik to the malware in question:
An investigator with the international police organization Interpol told the court that with the help of the U.S., which provided data from BTC-e, it appeared that most of the ransom payments were sent to an account that was linked to Vinnik.
He would obviously be useful to the authorities in solving various ransomware and money laundering cases, but I haven't exactly seen a compelling case against him, in regards to the allegations that he owned BTCe or developed and distributed Locky.
