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.

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.
