Alan Ralsky, a 64-year-old Michigan man that federal investigators say was among the world’s top spam kingpins, pleaded guilty on Monday to running a multi-million dollar international stock fraud scam powered by junk e-mail. Ralsky (pictured at right, courtesy of Spamhaus) and his son-in-law and chief financial officer Scott K. Bradley, 38, also of Michigan, pleaded guilty to conspiracy to commit wire fraud, money laundering and to violate the CAN-SPAM Act. Under the terms of his plea agreement, Ralsky faces as much as 87 months in prison and a $1 million fine, while Bradley could get as much as 78 months in prison and a $1 million fine under the federal sentencing guidelines. The Ralsky plea caps a long effort by the government to nab one of the most prolific spammers. In September 2005, the FBI raided Ralsky’s home, but it wasn’t until early 2008 that the government indicted Ralsky
