ALEXANDER SHATOV-UNSPLASH

UTAH sued Chinese-owned app TikTok on Tuesday, accusing it of harming children by intentionally keeping young users spending unhealthy amounts of time on the short-video sharing platform.

The Utah suit is the latest action challenging the popular app in the United States, with Indiana and Arkansas bringing similar suits.

Last month, a federal judge blocked California from enforcing a law meant to protect children when they use the Internet.

鈥淲hat these children (and their parents) do not know is that TikTok is lying to them about the safety of its app and exploiting them into checking and watching the app compulsively, no matter the terrible effects it has on their mental health, their physical development, their family, and their social life,鈥 said Utah Attorney General Sean Reyes in a filing.

Utah鈥檚 suit filed in state court said the videos leverage 鈥渉ighly powerful algorithms and manipulative design features 鈥 many of which mimic features of slot machines鈥 and the result 鈥渙f these manipulative tactics is that young consumers become hooked.鈥

ByteDance-owned TikTok, which has more than 150 million US users, said in response to the suit it 鈥渉as industry-leading safeguards for young people, including an automatic 60-minute time limit for users under 18 and parental controls for teen accounts.鈥

Mr. Reyes said the state鈥檚 investigation is ongoing and he will ask a court next week to compel TikTok鈥檚 compliance with investigative subpoenas.

Utah is seeking civil penalties as well as an injunction prohibiting TikTok from violating state law that protects consumers from deceptive business practices.

Indiana鈥檚 lawsuit against TikTok, brought in December, is pending in state court.

Arkansas also sued both TikTok and Facebook-parent Meta in March 鈥渇or pushing addictive platforms.鈥

Last year, a group of Republican lawmakers said that 鈥渕any children are exposed to non-stop offerings of inappropriate content that TikTok鈥檚 algorithm force-feeds to them.鈥

On Thursday, a judge will hear arguments in TikTok鈥檚 lawsuit seeking to block Montana鈥檚 first-of-its kind state ban on the use of TikTok before it takes effect Jan. 1. Montana鈥檚 legislature approved legislation to ban TikTok citing spying concerns.

Congress has been considering legislation for months that would enable the Biden administration to restrict or ban TikTok over concerns of potential spying. TikTok has said it has spent more than $1.5 billion on rigorous data security efforts and rejects spying allegations. 鈥 Reuters
