The Crime: Unlawfully accessing a computer without authorization and sending multiple e-mails; resending multiple commercial email messages with the intent to deceive recipients; or falsifying header information in multiple email messages.

The Time: Spam and its decedents are not only extremely annoying, they are federally outlawed. This shady practice carries a maximum five year sentence if the sender is spamming for commercial gain. In all other cases, spammers face a possible three year sentence for their first offense. Thank you, Gmail.
