It would strike me as odd that folks that went to the lengths stinc did to control the currency, and create 100's of 1000's zombie accounts to appear popular, would not still control a sizable percentage of the hive on the exchanges.
In fact, any anonymous accounts in the top 1000 are likely controlled by far less than 1000 people.
I'm not sure that all the stincy moles are gone, yet.
