Caribbean Cruise Line Inc. has agreed to a $7.73 million settlement after the Federal Trade Commission (FTC) and 10 state attorney generals sued the Fort Lauderdale-based company for disguising illegal sales calls as legal political survey robocalls. The company will pay $500,000 of the fine and the rest will be partially suspended. Political survey robocalls to landline phones are exempt from the FTC's do-not-call and robocall rules because they aren't used to sell anything. The FTC said that Caribbean Cruise Line Inc. made billions of robocalls to sell cruise packages between October 2011 and June 2012, which included between 12 and 15 million calls per day.
