What user data has been leaked from MtGox's database during June 2011 hack?
It was details of 61016 user accounts as a CSV file with fields UserID,Username,Email,Password.  The passwords are hashed, and most of them salted too, but some (the oldest) are simple md5 hashes.

I just tried searching google for it and was unsuccessful.

I have a copy, and could make it available for download but don't know if that would be legal.  I'm guessing not.
