The Kardashians are accused of breaking advertising rules on Instagram

The Kardashians are famous for broadcasting their lives on social media — but one advocacy group said they don't share enough. Truth in Advertising sent a letter to Kris Jenner and dozens of associated brands alleging the Kardashians repeatedly failed to disclose when Instagram posts were paid for by advertisers — violating the Federal Trade Commission's rules. FTC rules say the paid posts must be clearly marked as such in order to avoid deceiving potential customers.
