Senators Olympia Snowe (R-Maine) and Bill Nelson (D-Florida) introduced the m-SPAM Act which will update the CAN-SPAM law to include text message spam. If it passes, marketers will be explicitly barred from sending text messages to any mobile number on the national Do-Not-Call Registry maintained by the FTC.
The lawmakers cite the possibility that mobile spam could spread viruses and the way this spam affects monthly cellphone bills. According to Snowe, mobile users received 11.1 million spam messages in 2007 (up 38% from the previous year).
