Amir is on of the guys of the Bitcoinica / Interscamgo debacle leaking the Bitcoinica source code which ultimately led to another hack on the platform. People still try to get back tens of thousdands (!) of Bitcoins now kept hostage at MtGoxScam even though court-appointed liquidators have been claiming these funds for over a year now. It is being speculated that MtGox may have used these coins and the money to avoid insolvency up to today. (see https://bitcointalk.org/index.php?topic=451225.0;topicseen Mt.Gox SCAM? $38million disappeared. Large sums affected.)

He should be the last person to have anything still to do with Bitcoin, let alone be a spokesman. I wish he was in jail.
