Short answer: “Bloody Friday” (October 9, 2026) was a rumor about an alleged nationwide challenge in Polish schools, which the police did not confirm, but which nevertheless kept many children at home. It showed how quickly fear spreads on social media. The best protection for a child consists of three things at once: conversation and shared rules at home, safety settings (e.g., Family Pairing on TikTok), and the habit of checking information before sharing it.
This article complements our guide How to teach a child to search for information in the era of TikTok and Reels. There you’ll find search techniques; here we focus on safety, parental supervision, and disinformation, using recent events as an example. With such a difficult topic, we separate what is confirmed from what is our advice.
Bloody Friday: what we know and what we don’t
On Wednesday, October 7, and Thursday, October 8, 2026, there were dangerous incidents in schools: in Ostrołęka a 19-year-old attacked nine people with a knife, and in Leszczydół-Nowiny near Wyszków a 15-year-old injured three people and a 37-year-old school custodian was killed (data from Do Rzeczy). In this context, information about a “Bloody Friday,” the alleged culmination of the violence, began circulating in student and parent groups. According to Polsat News, many children did not go to school on Friday, October 9.
| Claim | Status according to available sources |
|---|---|
| Attacks in Ostrołęka and Leszczydół-Nowiny | Confirmed in media reports (Do Rzeczy) |
| A nationwide “challenge” for Bloody Friday exists | Not confirmed: police said there was no indication of it (Polsat News, October 9) |
| A video announcing an attack (“the knifeman from Przasnysz”) | According to police, the recording was generated by artificial intelligence; a 17-year-old who is probably the author was detained (authorship unconfirmed at that stage) |
| Practical consequences | Schools in Ciechanów and Pułtusk canceled classes (Do Rzeczy) |
| Scale of police action | Polsat News: over 10,000 schools checked and 10 people detained; a TVP headline from a later publication mentions 35,000 schools and dozens of detained teenagers |
Police appealed for calm and for people not to repeat unverified information, and reminded that those deliberately causing panic may face criminal liability (Polsat News). Wojciech Kardyś, quoted by Benchmark.pl, points to two mechanisms: fear, especially for children, clouds logical thinking, and when we skim, we skip words like “alleged,” so only the “challenge” stays in memory. Even people who want to warn others can fuel panic this way.
A lesson for parents: a real tragedy, a rumor, fear, and an AI-generated video combined into an event in which it was hard to quickly tell facts from disinformation. A child who can stop and check is safer, and not only psychologically.
Is there reliable information on TikTok?
In short: sometimes, but the platform is not designed as a news source; it’s a stream of entertainment tailored to grab attention. Some data:
- Reuters Institute (Digital News Report 2025): TikTok is the fastest-growing platform in the news category (up 4 percentage points across all markets surveyed), and users consider it one of the biggest threats to the reliability of information (according to Demagog’s summary).
- NewsGuard (September 2022): 20% of news search results on TikTok contained harmful disinformation, including about the war in Ukraine and health (via Demagog). This data is a few years old, but it shows the scale of the risk.
- NASK as summarized by Demagog (2023): almost one in three teenagers never checks whether information or its publisher is credible, and 65% believe it’s impossible to tell truth from falsehood online. Trust in the source or in someone they know plays the main role in judging credibility.
Takeaway: on TikTok you’ll find reliable accounts of institutions, newsrooms, scientists, and fact-checkers, but a child should treat a video as a signal to check, not as proof.
What the algorithm does: the CCDH experiment and “patostreams”
The algorithm learns from every second of viewing. In its report “Deadly by Design” (2022), the organization CCDH set up 8 accounts posing as 13-year-olds in four countries. After 30 minutes of watching and liking content about mental health and weight, the results were alarming (description via Demagog):
| Indicator | Result |
|---|---|
| First video about self-harm or suicide | in less than 3 minutes |
| Eating disorder content | after about 8 minutes |
| More similar content after interaction | about every 39 seconds |
| Accounts of “vulnerable” teens | 3 times more eating disorder content and 12 times more self-harm content than standard accounts |
The second threat is time and extreme content. According to NASK as summarized by Demagog (2023), teenagers spend an average of 5 hours 36 minutes online on weekdays, and about a quarter watch “patostreams” (shock live streams featuring degrading behavior); boys do so almost twice as often as girls, and teenagers watch them twice as often as their parents think. Note: NASK reports are published in successive editions with different numbers, so check the original if you quote the data further.
Who should supervise what a child does online?
The answer is: parents first and foremost, but not only them. Responsibility is shared:
| Who | What they’re responsible for |
|---|---|
| Parents and guardians | Rules at home, conversation, account settings, being available when the child is scared or sees something |
| School | Media education, responding to threats and cyberbullying, a clear information channel for parents (instead of rumors in messaging apps) |
| Platforms | Minimum age, privacy by default, limiting addictive mechanisms. The European Commission’s guidelines for the DSA (Art. 28) point to the highest privacy as the default and to limiting addictive algorithms and notifications |
| The state and police | Responding to threats, public announcements, prosecuting those who cause panic |
| The child | Gradually increasing responsibility for their own choices, as they get older |
Why isn’t “the platform will take care of it” enough? Because the EU guidelines are only now coming into force, and age verification through the European digital identity wallet is to be available in all EU countries by the end of 2026 (according to Gazeta Prawna). Today, home is still responsible for many things. According to the 2019 edition of the NASK report “Teenagers 3.0,” most families did not set rules limiting time or content, so the actual situation is often worse than what people declare.
What you can realistically set up on TikTok
According to the Internet Matters guide (check in the app, because features change):
- The minimum age for an account is 13. Accounts for ages 13–15 start as private, but a teen can change this unless a parent uses Family Pairing.
- Family Pairing: the parent generates a QR code or link, and the teen accepts it. The parent can then manage screen time, notifications, content, and who can contact the child.
- Time: the shortest daily limit in the app is 40 minutes; you can set “downtime” (e.g., school hours, night). Without pairing, accounts for ages 13–17 have a default limit of 1 hour a day, which the child can change themselves.
- Night: for users under 16, the “For You” feed is muted after 10:00 p.m., and notifications are turned off at night.
- Content: restricted mode, keyword filters, a STEM feed; a parent can also restrict comments, mentions, and duets.
Remember that these are supporting tools. Technology won’t replace conversation, because children can get around restrictions, and trust matters more than control.
What should you allow your child, and what should you forbid?
The table below is our practical proposal, not a regulation or an institutional recommendation. Adjust it to your child’s maturity.
| Age | Allow | Forbid or limit |
|---|---|---|
| Under 12 | Watching selected videos together with a parent; searching for school information with an adult | Their own TikTok account (the terms require age 13); browsing the endless feed alone |
| 13–15 | A private account with Family Pairing enabled; a time limit; contact with friends from real life | A phone in the bedroom at night; talking to strangers; sharing their school, address, and daily schedule; sharing alarms without checking |
| 16–17 | More independence, an agreement instead of bans, reviewing settings together every few months | Patostreams, self-harm and extreme diet content, hate, sending intimate photos |
- Always allowed: coming to a parent with a disturbing video, without punishment and without taking the phone away “as a consequence.”
- Always forbidden: posting or forwarding threats, even “as a joke.” Police remind that causing panic can result in criminal liability, and teenagers were detained in the Bloody Friday case.
- Phone at night: keeping the charger outside the bedroom is one of the simplest rules, and it helps both with insomnia and with anxiety after alarming content.
How to teach a child to tell truth from fake: 6 steps
Children learn best from examples from their own lives. Use Bloody Friday as a lesson: ask what your child saw and heard, and go through the steps below together. The steps are our own compilation, based on advice from Demagog and fact-checkers.
Stop: name the emotion
Before your child forwards anything, have them ask themselves: “did this scare me or make me angry?” The expert quoted by Benchmark.pl reminds us that fear clouds logical thinking, so that’s exactly when you need to slow down.
Check who is saying it
Look at the account: does it have a verification badge, what other posts does it have, does it usually publish sensational content? Demagog advises reviewing the account’s history for a pattern of emotional, sensational content.
Step outside TikTok
Open a new tab and check the statement from the police, the school, or a newsroom. In the case of Bloody Friday, it was the police who first said there was no indication the challenge existed. We describe checking techniques in our guide on searching for information.
Look for the words “alleged” and “reportedly”
Such words often get lost in the message, yet they change the meaning. Practice together: read a headline and mark the words that reduce certainty.
Check the image and sound
A video may have been generated by AI, like the Bloody Friday recording according to the police. Look for unnatural mouth movements, a missing source, and the absence of the same footage elsewhere. More in our article on recognizing deepfakes.
Don’t share, report
If someone is really making threats, report it to an adult and to the police (emergency number 112 in Poland, 911 in the US) instead of posting it further. Sharing it “as a warning” alone can fuel panic.
Trends and threats worth watching out for
- Viral alarms and “challenges”: rumors about alleged actions that grow through sharing. Bloody Friday is an example here, because police did not confirm the challenge existed, yet the consequences were real.
- AI-generated content: fake recordings of threats and fake “reports” are hard to tell apart at first glance.
- Algorithmic rabbit holes: content about self-harm, eating disorders, and extreme dieting, often under coded hashtags (CCDH, via Demagog).
- Patostreams: watched by about a quarter of teenagers, according to NASK as summarized by Demagog.
- Cyberbullying: most often name-calling, and the most common reason for attacks is appearance (NASK, according to Demagog). According to the same summary, about one third of teenagers had been insulted, and almost a quarter ridiculed or humiliated.
- Health and political disinformation: short formats make oversimplification and emotional narratives easier.
How to talk with your child after a wave of fear like this
Below is our practical advice, built on the principle that a child should feel safe and capable:
- Start with questions, not a lecture: “what did you hear about Friday?”, “how do you know?”. Don’t make fun of their fears.
- Say what is known and what isn’t: the attacks in Ostrołęka and the surrounding area were real, but the existence of a nationwide challenge was not confirmed by the police.
- Give a plan: who your child will go to at school, how they’ll contact you, how to report a threat. A sense of control reduces anxiety.
- Decide together to limit stimuli: less browsing of sensational content that day, more talking and physical activity.
- Don’t punish them for bringing bad news: a child who is afraid to show a parent a disturbing video will show it to someone else.
- Set a good example: don’t forward unverified alarms in family groups yourself.
Frequently asked questions (FAQ)
It was a rumor about an alleged online challenge for teenagers that was supposed to be the culmination of violence in Polish schools on Friday, October 9, 2026. Police said there was no indication that such a challenge existed, but many children did not go to school that day.
The school attacks in Ostrołęka and Leszczydół-Nowiny did take place, but the police did not confirm the existence of a nationwide challenge. The video announcing an attack, according to the police, was generated by artificial intelligence.
Sometimes, especially on the accounts of institutions, newsrooms, and experts. However, the platform is not designed as a news source, and research (including NewsGuard in 2022) found a high share of disinformation in news results. Treat a TikTok video as a signal to check, not as proof.
According to Internet Matters, the minimum age is 13. Accounts for ages 13–15 are private by default, but a teen can change this unless a parent turns on Family Pairing.
Parents and guardians first and foremost, but responsibility is shared with the school, with platforms, which must meet the requirements of the Digital Services Act, and with the child, who learns independence with age.
Turn on Family Pairing: the parent and child link their accounts with a QR code or link. Then you can set a time limit (the shortest is 40 minutes), app-free hours, restricted mode, keyword filters, and limit contact. Features may change, so check them in the app.
No. They are a supporting tool. Children can get around restrictions, and the algorithm can show difficult content quickly. Conversation and trust are what matter most.
Teach six habits: pause when emotions run high, check the author, step outside TikTok, pay attention to the words “alleged” and “reportedly,” check the image and sound for AI, and don’t share without verifying.
Stay calm, don’t punish your child, save the link and a screenshot, report the matter to the school and the police, and in an emergency call 112 (911 in the US). Talk with your child about how they feel.
Police warned that people who deliberately cause panic may face criminal liability, and teenagers were detained in the Bloody Friday case. Specific laws and penalties depend on the circumstances, so if in doubt, it’s worth consulting a lawyer.
Viral alarms and fake challenges, AI-generated content, algorithmic “rabbit holes” with self-harm and eating disorder content, patostreams, and cyberbullying.
That’s a family decision. A ban can be effective for younger children (under 13 the terms require it anyway), while for teens it often moves the activity to hidden places. An agreement tends to work better: a private account, a time limit, no phone at night, and open conversation. This is our opinion, not an institutional recommendation.
In Poland, the helpline for children and young people is 116 111. In a life-threatening emergency call 112, and for mental health problems contact a doctor or psychologist. (In the US: call or text 988, or call 911 in an emergency.)
