Imagine your teen taps a button that promises a fresh start for their feed. The app says it worked. Nothing changes. That’s the core of the newest twist in the tiktok lawsuit new york filed against the company, and it’s landing hard with parents this week.
Here’s the short answer. Newly unsealed portions of New York’s case allege that TikTok repeatedly gave thousands of users, including teens and children, a non-working “placebo” version of its Algo Refresh feed-reset tool in 2023, while other users got the real thing. TikTok says it was routine product testing and that the claims mischaracterize how the feature works.
These are allegations, not findings. Still, they raise a fair question: do the safety buttons in your kid’s apps actually work? Let’s break it down.
| Key fact | Details |
|---|---|
| Who is suing | New York Attorney General Letitia James |
| Original lawsuit | Filed October 8, 2024, as part of a 14-AG bipartisan coalition |
| New allegation | Some users who turned on Algo Refresh got a placebo version that didn’t change their feed |
| When the tests allegedly ran | Repeatedly in 2023, on thousands of users |
| What TikTok allegedly measured | Time spent on the app and ad revenue |
| How it became public | Amended complaint filed under seal in late August 2026, later ordered unsealed |
| TikTok’s position | Says it regularly tests features and denies the allegations |
What the tiktok lawsuit new york filings now allege
The new details come from an updated complaint that New York filed under seal at the end of August, which a judge later ordered unsealed, according to Reuters reporting carried by WMBD. The headline claim is about a feature called Algo Refresh, which TikTok promoted as a way to reset recommendations for people trying to get away from unwanted or harmful content.
According to the complaint, some users who switched it on received a version that did nothing. They believed their feed had been reset. It hadn’t. TikTok then allegedly compared those users with people who got the working version, looking at how long each group stayed on the app and how much ad revenue they generated.
Why does that matter? A reset button is often the first thing a worried teen reaches for when a feed turns dark. If it’s quietly switched off, they have no way to know.
The key takeaway here is simple: the allegation isn’t just that a feature was tested, it’s that people trying to protect themselves may have been part of the control group.
An internal objection, according to the complaint
The filing also describes pushback from inside the company. A TikTok product manager for Digital Well Being reportedly called the placebo tests problematic and warned that users might find them misleading.
“This feature is about algorithm transparency and control. A placebo group completely conflicts with that.” — a TikTok product manager, as quoted in the New York complaint via Reuters
A second set of experiments
The unsealed portions go further. They allege TikTok randomly selected users and turned off safety features that limited exposure to harmful content, something Bloomberg had reported earlier. According to Bloomberg, a New York teenage boy in one of those test groups died by suicide after being shown what internal reviews described as an “onslaught” of self-harm and suicide content. If you or a teen in your life is struggling, you can call or text 988 to reach the 988 Suicide & Crisis Lifeline in the US.
Claims Journal’s report, citing a Bloomberg Businessweek story based on a confidential TikTok document, adds scale: an algorithmic test that began in 2021, touched about 15 million US users, and withheld a new safety feature from 10% of US users to see whether it cut time spent on the platform. Those figures haven’t been tested in court.
What TikTok says in its defense
Fairness matters here, so let’s give TikTok’s side its full weight. A company spokesperson said, “We continuously make improvements to our platform,” and explained that, like most companies, TikTok regularly tests new products to understand how they work in the real world. The spokesperson also said the allegations mischaracterize how Algo Refresh works.
In a court filing, TikTok confirmed it runs tests that “may involve a portion of platform traffic that continued to receive the original experience,” according to Claims Journal. It denies those tests make the platform less safe for the people in them. More broadly, TikTok has denied New York’s allegations and says keeping young users safe is a priority.
Is A/B testing normal? Yes. Nearly every big app does it, including the ad experiments covered in our look at ChatGPT ads. Here’s the catch. Testing a new button color is one thing. Testing whether a safety tool works by giving some people a fake one is a very different question, and that’s exactly what a judge will be weighing.
“A safety switch only counts if it works every time you flip it.”
How the case got here: a timeline
This didn’t start this week, and the case has already survived an early attempt to throw it out.
| Date | What happened |
|---|---|
| October 8, 2024 | New York and California lead a bipartisan coalition of 14 attorneys general suing TikTok, each in their own jurisdiction |
| May 2025 | New York’s suit largely survives TikTok’s motion to dismiss, with one set of claims cut, per MLex |
| Late August 2026 | New York files an amended complaint under seal with experiment details |
| September 2026 | TikTok settles Alabama’s case for up to $300 million and agrees to teen-focused changes in that state |
| October 7–8, 2026 | Unsealed filings reveal the placebo Algo Refresh allegations |
Let’s back up a little. The 2024 suits accused TikTok of addictive design, from round-the-clock notifications to beauty filters. New York’s own suit specifically claimed that its “Refresh” and Restricted Mode features didn’t work as advertised, and that the 60-minute screen time limit could be bypassed with just a passcode.
Fast forward to now. The placebo claims put hard detail behind that 2024 complaint about Refresh. In other words, the new filings don’t change what New York is arguing, they add evidence for it.
What Algo Refresh is supposed to do
TikTok introduced a way to refresh the For You feed back in 2023. According to Search Engine Journal’s March 2023 coverage, the reset was designed to make your feed behave as if you’d just signed up for a new account, with future recommendations built from your new activity. It doesn’t wipe other content preferences, such as keyword filters or creators you’ve hidden.
New York’s complaint challenges that pitch too. It alleges TikTok misled users by saying Algo Refresh would reset their recommendations when the change was only temporary. TikTok disputes that characterization.
So what’s the lesson? A feed reset can help, but treat it as one tool among several.
Real TikTok safety settings parents can use today
You can’t control the courtroom, but you can control your family’s settings. These steps come from TikTok features described by Internet Matters and TechCrunch, so menu names may shift slightly by app version.
1. Link accounts with Family Pairing
Family Pairing connects your TikTok account to your teen’s so you can manage settings from your own phone. Go to Profile, tap the three lines at the top right, open Settings and privacy, then Family Pairing. Choose the parent role, and have your teen scan your QR code or open your link on their device to confirm.
2. Turn on Restricted Mode
Inside Family Pairing, open your child’s account and go to Content preferences, then switch on Restricted Mode. It limits content that may not suit all audiences and stops your teen from logging out or switching accounts to get around it.
3. Add keyword filters together
Also in Content preferences, you can add keywords tied to content that might affect your child’s wellbeing. Do this with your teen, not to them.
4. Set a screen time limit that sticks
Teens aged 13 to 17 get a default 60-minute daily limit, but they can enter a passcode to keep going. With Family Pairing, you can set your own daily limit, with different limits for different days, down to a minimum of 40 minutes. You can also schedule muted notifications.
5. Lock down privacy
Accounts for ages 13 to 15 are private by default, but teens can switch that off unless Family Pairing blocks it. In Privacy and safety, turn on Private account and turn off suggesting your teen’s account to others. Then set contact options to Friends or No one.
6. Refresh the feed, then check it
If a feed has gone somewhere unhealthy, go to Settings and privacy, then Content preferences, then Refresh your For You feed. Afterward, check with your teen that the feed actually changed.

What could happen next
New York’s case is moving separately from the giant consolidated proceedings against Meta, TikTok, Snap and YouTube, according to Claims Journal.
Settlement is a real possibility. TikTok paid Alabama up to $300 million last month and agreed to change how the app works for teens there. Meta, meanwhile, reached a settlement with nearly every state worth up to $18 billion, and a $5.3 billion slice of that depends on whether TikTok and Snap commit to similar changes.
You see, the bigger trend is clear. Regulators are no longer just asking whether platforms have safety tools. They’re asking for proof those tools work, much like the scrutiny now aimed at data handling after incidents such as the ShinyHunters FBI breach and the rise of deepfake-as-a-service scams targeting families.
Here’s what to watch:
- Court rulings: whether the judge allows the placebo evidence to go before a jury.
- Settlement talks: whether New York follows Alabama with a deal that includes product changes.
- Other states: whether similar experiment claims appear in the more than two dozen other state suits.
- Feature changes: whether TikTok revises how Algo Refresh works or how it’s described.
Where this leaves your family
None of this has been proven yet, and TikTok will get its chance to explain the tests in court. But the case is a useful reminder that a safety setting is a promise, and promises deserve to be checked.
The good news? You don’t have to wait for a verdict to act. Pair accounts, set limits, filter content, and talk with your teen about what their feed feels like. The best safety feature in any app is still a parent who’s paying attention.

Frequently asked questions
New York argues that TikTok designed its app to be addictive for young people and misled the public about how safe it is. The original 2024 complaint pointed to features like constant notifications, autoplay and beauty filters, and claimed safety tools such as Refresh and Restricted Mode didn’t work as advertised. The new filings add the placebo Algo Refresh allegations.
Not directly. This is an enforcement action brought by the New York Attorney General on behalf of the state, not a class action that individuals join. If you have concerns about harm to your child, you can contact the attorney general’s office or speak with a lawyer about other options.
The reset, which TikTok calls refreshing your For You feed, was described in 2023 as making recommendations start over as if you’d opened a new account. It keeps your keyword filters and hidden creators. New York alleges the effect was only temporary, and that some users got a version that did nothing, which TikTok disputes.
No. TikTok says it regularly tests new products and features, like most tech companies, and that the allegations mischaracterize how Algo Refresh works. In a court filing it confirmed some tests leave part of its traffic on the original experience, but it denies this made the app less safe.
There’s no sign of that right now. In January 2026, ByteDance announced a new US joint venture, TikTok USDS Joint Venture LLC, with American and global investors holding 80.1%, a deal described as designed to avoid a US ban. This New York case is about child safety, not about whether the app stays available.
Start with Family Pairing, then turn on Restricted Mode, set a daily screen time limit and add keyword filters together with your teen. Make sure their account is private and contact settings are limited to friends. Check their feed after any refresh to confirm it actually changed.
