Massachusetts Attorney General Andrea Campbell filed a lawsuit against TikTok on Tuesday, allegedly the massively popular social media company has deliberately exploited young users.

Massachusetts is the latest state suing TikTok claiming the company designed its app to keep underage users addicted to the content. Why it matters: TikTok has faced scrutiny in recent years over whether its algorithm is causing adverse mental health effects in teenagers.

Massachusetts has joined more than a dozen states in suing TikTok, claiming the app's design causes addiction and harms the mental health of young users.

Massachusetts is one of more than a dozen states and the District of Columbia who sued Tiktok Tuesday, claiming the company's conduct violates state consumer protection laws and harms kids' mental health.

TikTok designed its social media platform “to be addictive and harmful to young users” and deceived the public about efforts to keep the app safe, Attorney General Andrea Campbell alleged in a new lawsuit.
