That said, I do think he absolutely deserved to be released, not because he didn't deserve to be locked up in the first place, but because he's clearly been rehabilitated and has done great work during his time in prison. All that considered, ten years seems like a not unreasonable prison sentence for what he did. I hope he'll continue to do good when he's released.
Those allegations were used to deny him bail and influenced public perception, they were not part of his formal conviction or sentencing.
He was convicted on non-violent charges related to operating the Silk Road website, including drug distribution, computer hacking, and money laundering.
Does this change your opinion of sentencing being well-deserved?
Is it? Preponderance of the evidence is basically “more likely than not”
A preponderance of the evidence is the greater weight of the evidence after all evidence is considered. Heuristics along the lines of "yeah that fits my priors"—which is what is actually meant by "more likely than not"—are explicitly disallowed.
If Joe Smith in Smalltown, Ohio was hit by a blue bus, and hammock owns 51 of the 100 blue buses in Smalltown whereas torstenvl owns 49 of the 100 blue buses, that is insufficient evidence by itself to prevail by a preponderance standard against hammock in a civil suit.
