Metric: 43% of all US SMS messages are spam

[via Fierce Wireless]
According to findings from Wireless Services Coporation, 43 percent of all mobile text messages in the US are now spam. That's almost double from 2003, when only 18 percent of text messages in the US were spam. In December alone SMS spam accounted for roughly 1.2 billion messages blocked by Wireless Services. The growth of mobile spam is being caused by spammers who are now branching out beyond traditional email to the wireless market, where they are specifically targeting mobile addresses.
