Danfuzz is the long-time nickname for Dan Bornstein. He has been around the net in one form or another since the late 1980s. In 1994, with the Internet looking to be here to stay, he acquired the domain name milk.com as his homestead on the net. As of this writing, he still maintains a net presence using that domain.
Danfuzz' brother is User:Jeremybornstein.
