Microsoft recently filed seven new lawsuits against spammers for allegedly using third-party PCs to send sexually explicit spam messages that violate rules set down by the CAN-SPAM law and the Federal Trade Commission (FTC). This follows on previous action by Microsoft and Amazon, who filed several joint lawsuits during the summer against phishers and spammers “spoofing” the domain name to encourage unsuspecting consumers to divulge personal information.

The lawsuits claim that the spammers violated several U.S. federal laws, based on three allegations:

– sending spam email via compromised computers

– failing to include an unsubscribe option or physical mail address and

– neglecting to warnrecipients that the email included sexually explicit material.

It is alleged that hundreds of thousands of spam messages were sent.
