Pennsylvania Attorney General Dave Sunday sued Snapchat's operator over claims that the app uses addictive designs and misrepresents content suitability to parents. The complaint alleges violations of Pennsylvania's Unfair Trade Practices and Consumer Protection Law. The filing says Snapchat misrepresents the frequency of adult-themed material while seeking a 13+ rating that parents rely on. Snapchat said the allegations misrepresent its platform and pointed to existing safety tools.
