Washington state Attorney General Rob McKenna's office has filed a lawsuit targeting a Florida-based company that sends people unsolicited text messages, calling it another form of spam that annoy and cost consumers.

The attorney general's offices filed the lawsuit this past Thursday in federal court in Seattle, adding on Monday that it's one of the first lawsuits by a state attorney general targeting spamming through text messages.

McKenna's office is targeting Orlando-based Dinav Holding. It alleges the company over a period of two days in May targeted residents in Washington with texts advertising payday loans with companies not licensed in the state.

McKenna's office says Dinav Holding violated the federal Telephone Consumer Protection Act and two state consumer protection laws.

A phone number listed for Dinav Holding rang busy.
