Given the farcical nature of those allegations and all that we now know, including that others with access to the Dread Pirate Roberts account assert that the DEA agent making the allegations (who is himself now in prison for attempting to steal some of the silk road bitcoin) had access as well, it will be wonderful if DoJ attempts to bring charges, just to further clear Ross' name.

There are not a shred of evidence that Ross ever had the slightest thing to do with those conversations, and it seems much more likely that the DEA used the DPR account to frame him.

Wasn't charges about paying a hitmen dropped?

IIRC it was to do with the conduct of the FBI agents posing as hitmen? I think they ended up in prison too, so a prosecution would be hard.

Seems like it.
