I learnt about bitcoin following some press articles about the Silk Road. As a result I would love some free bitcoins, so that I can exchange them for hash.
Thanks love

Even though the other accounts are inactive or no longer used, what is clear is that all three of them are connected to the same address.
Regarding buying and selling, I didn't find strong evidence for that, it could have been bought by another user or sold by the original owner, considering that @tinyteapot has more than one account here, but some other evidence if there is is very good for prove accountit is sold to someone else.
For the time being only connected evidence can be proven.
