The pair were ridiculed for their alleged participation in the fraud on the front cover of the satirical magazine Private Eye. On 10 September 2008, Ant & Dec announced that the frauds "will never happen again", insisting that a "high-tech system" and strict rules will ensure viewers cannot lose out with poorly monitored premium rate phone lines. On 30 September 2008, it was reported that Ant & Dec were being sued for $US30 million by Greek American stand-up comedian and actor ANT for using the name 'Ant' in the United States.
