Amir Taaki talking about the multiple personas DPR moniker:
http://www.miningpool.co.uk/amir-taaki-backs-up-ross-ulbrichts-claim-of-leaving-silk-road-after-creating-it/Years ago, when I messaged the Silk Road, I had a conversation with the Dread Pirate Roberts a very personal conversation where he was [talking] about how one day he hopes to be on the outside struggling for freedom together. You know, not having to hide his identity. One year [or] two years later when I messaged the guy Im pretty certain it was not the same guy. The tone was completely different. He had no recollection of the events that happened before, and his attitude to me was in stark contrast to the exuberant and wordy Dread Pirate Roberts of the early days. So, free Ross Ulbricht.
I have no reason to believe this and at the end of the day it's just his opinion. Ross was caught red handed both in setting the site up and running it when he was caught do I don't really buy the different person excuse.
