How? within the last 7 days, multiple accounts fit the discription.
Created in first half of 2011, 1000+ activity with a nice, self made, unique avatar. I don't see any like that which have changed the password recently.
He said around 1000 activity iirc. Also mid 2010-mid2011, I don't find where he said it was exactly first half 2011. Also on Oct 27 someone fits the description. I bet if he sells it within 2 months, there is no way someone can say without doubt.
