Has anyone tried and perhaps succeeded at linking a transaction to a possibly controversial site (such as Wikileaks) to a Bitcoin forum user by their forum signatures? I know a lot of people disclose their Addresses, and since the WikiLeaks address is well known, one would probably just need some webcrawler and be able to make a connection. Has anything like this ever been done?
This article was written regarding the alleged theft of 25,000 BTC in July 2011. A similar analysis could be done using known addresses and identities, I would imagine.
