An anonymous reader writes "The Australian Communications and Media Authority has commenced legal proceedings in the Federal Court against several local and international companies over allegedly unsolicited SMS spam. It's the first time the regulator has used its powers under the Spam Act to pursue an alleged SMS spammer through the Courts. Other companies have been fined or committed to an 'enforceable undertaking' to avoid this type of action (although these are not without issue). Another firm accused of SMS spam accused the regulator of being overzealous after it received a formal warning. The regulator appears to have instituted a crackdown on the premium mobile content industry in recent months, culminating in this latest action."
