If you lost money in this scheme and are in the United States or Canada, contact your state securities regulator [1]. Mention any such referral sources. Those individuals may be liable for securities fraud under state and federal law.
If you're in the United States, send a copy to the SEC [2]. If you lost more than a token amount, I would also recommend contacting an attorney.
