SILICON BEAT - Sep 17 - Yelp has agreed to pay a $450K to settle Federal Trade Commission charges. The FTC has gone after Apple, Amazon and Google for instances when children allegedly rung up charges as part of in-app purchases. In Yelp’s case, the company asked users for their date of birth. A few thousand people gave ages showing that they were under 13. Yelp not only didn’t block those people but it collected their e-mails, addresses and locations. Yelp violated the Children’s Online Privacy Protection Act (COPPA) which prohibits collecting data on children under 13. Yelp failed to test its technology.
