That explains why Bitblender had to shut down voluntarily and hurriedly wiped of their servers
They must have smelt a rat on realizing the gravity of the situation. I never used bestmixer but it's quite surprising that they kept transaction logs
They may have kept transaction logs, but this is *probably* irrelevant here. The police didn't just immediately shutdown their servers. They kept it running as a honeypot for a while to gather these logs. Bestmixer didn't necessarily hold them before (while they weren't runned by the police).
