Silk Road 2.0

“Silk Road 2.0” (not a person)

Silk Road 2.0 was a darknet marketplace (an illegal online market reachable via Tor) that re-launched on November 6, 2013 as a successor to the original Silk Road after the original site was seized in October 2013. (en.wikipedia.org)

It was marketed as a continuation of the original site’s model (anonymous buyer–seller listings, prominently including narcotics), and it became one of the best-known darknet markets until it was seized and shut down on November 6, 2014 during Operation Onymous, a coordinated international law-enforcement action.

Who “ran” Silk Road 2.0 (key operators commonly identified)

Because these sites used pseudonyms, “who is Silk Road 2.0?” is usually understood as “who operated it?” The best-known alleged operator is:

• Blake Benthall (pseudonym “Defcon”) — widely reported as the operator/administrator of Silk Road 2.0 and arrested on November 6, 2014 in San Francisco in connection with the marketplace. (en.wikipedia.org)

Additional figures often mentioned in connection with its creation/administration include:

• A new, pseudonymous “Dread Pirate Roberts” identity associated with the relaunch, and other administrators (e.g., “Inigo” and “Libertas”) referenced in contemporaneous accounts of the site’s staff. (en.wikipedia.org)
• Thomas White (alias “Cthulhu”), described as a co-founder in some sources. (en.wikipedia.org)

If you meant a specific “Silk Road 2.0” username you saw online (rather than the marketplace), paste it and I’ll distinguish whether it refers to the site, an admin handle, or an unrelated impersonator.
