Seattle spammer gets 47-month sentence: There's an old saying that most criminals are stupid. That's certainly true of Robert Soloway, 28, who was sentenced to nearly four years in prison in July 2008 for his spamming activities. Soloway pleaded guilty to spamming, fraud and tax evasion. This was the third time Soloway ended up in court on spam-related charges. Soloway lost two previous law suits - filed by Microsoft and a US ISP - but kept on spamming.
