Anyone can generate a vanity address of arbitrary length with appropriate tools, it’s just a matter of performing enough computations. What is the longest known vanity address anyone has generated?
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?
